Q:TEN POINTS!! How is the catalyst affected by vinegar?
The catalyst is affected by vinegar because vinegar is acidic meaning there are more H+ ions. This alters the charges on the R groups of the amino acid residues of the enzyme molecule. The bonds that help maintain the conformation of the enzyme molecule which is ionic will therefore, be disrupted and the binding of substrate will be affected. However, if pH is restored to optimum pH, the maximum activity of the enzyme will be restored but this is only if the pH was only altered by a small extent. If pH is altered by a large extent, the conformation of the enzyme molecule will be severely affected causing it to denature. The catalyst is affected by heat because excessive heat disrupts the intermolecular bonds which stabilise the secondary and tertiary structure of an enzyme molecule(the enzyme molecule has a tertiary structure). The enzyme molecule unfolds and the precise shape of the active site is lost. This loss of structure and function is irreversible.
Q:What are the characteristics of the catalyst in the catalytic reaction?
The role of the catalyst in the chemical reaction is to change the rate of chemical reaction, and its own quality and chemical properties do not change.
Q:A catalyst elevates the rate of a reaction by?
Catalysts work by providing an (alternative) mechanism involving a different transition state and lower activation energy. Consequently, more molecular collisions have the energy needed to reach the transition state. Hence, catalysts can enable reactions that would otherwise be blocked or slowed by a kinetic barrier. The catalyst may increase reaction rate or selectivity, or enable the reaction at lower temperatures. This effect can be illustrated with a Boltzmann distribution and energy profile diagram. Take a look!
Q:The properties of scandium
Sci-Scandium (Sc) Basic knowledge Introduction In 1879, Swedish chemistry professor Nelson (LFNilson, 1840 ~ 1899) and Clive (PTCleve, 1840 ~ 1905) were almost simultaneously in rare mineral silica beryllium yttrium and black The mine found a new element. They named this element "Scandium" (scandium), ...
Q:On the issue of chemical balance and catalyst
Because the rate is scalar, it is not advisable to think too much from the speed change. I mean kv meaning that is proportional to the relationship, rather than proportional function relationship.
Q:how a catalyst can provide a new route in forming the product?
a catalyst does not provide a new route. a catalyst effects the rate of a reaction by lowering the activation energy required for the reaction - the number of successful collisions and reactions therefore increase and rate of reaction increases.
Q:How does active charcoal catalyze in some chemical reactions?
Activated carbon is generally in the catalytic reaction to do more carriers, has not yet seen its catalyst to report.
Q:What is a catalyst?
The catalyst plays a role in a variety of ways that are likely to temporarily alter the chemical changes associated with the reactants themselves, and may also only help to adsorb the physical changes in the reactants, but the reaction eventually becomes its own form The
Q:Question about catalysts and their function.?
Catalysts, as enzymes, only change the activation energy (the energy the compound needs to gain to transform into products), they don't change the Gibbs energy values of reactants nor products. Therefore, if the delta G of the reaction is positive, it'll still need free energy to complete. They make a reaction complete faster than in normal conditions, but don't change the actual possibility for that reaction to happen. In the human body, a lot of reactions of catabolism have a positive G value and these reactions needs to get energy from other coupled reactions that have a negative value, so the total value is still negative. Many of them use hydrolysis of ATP to provide that energy, as its hydrolysis is about -30 kJ/mol in physiological conditions. I don't know what class you're in to ask this question, so can't really know if this answer is too simple or complicated for u... sorry in advance! Joël
Q:High school stage chemical catalyst
Iron, manganese dioxide, mainly metal and its oxides.
