Q:How does the chemical equation calculate the quality of the catalyst?
Catalyst, the quality of the reaction before and after the same, the same chemical properties.
Q:What is chemical adsorption and its relationship with heterogeneous catalysis
The catalytic cycle includes five steps: diffusion, chemical adsorption, surface reaction, desorption and reverse diffusion.The chemical adsorption is an important part of the heterogeneous catalysis process, and the adsorption of the reactants on the catalyst surface,
Q:What is a Catalyst?
Catalyst is a chemical substance which is used in chemical reactions in relatively small amounts to start up or increase the rate of the reaction without being consumed in the process. For example, Sulfuric Acid is used to dehydrate Ethanol to Ethylene. Enzymes in living beings are biological catalysts. Manganese dioxide, used to decompose Hydrogen Peroxide to Oxygen and Water. For detailed answer.... en.wikipedia.org/wiki/Catalysis
Q:How does catalyst aid a chemical reaction?
Catalyst just speed up the chemical reaction they don't effect the chemical reaction or its equilibrium.............
Q:Several experiments were carried out using catalysts
Hydrogen peroxide in the manganese dioxide as a catalyst for decomposition reaction: 2H2O2 == MnO2 == 2H2O + O2 ↑ (laboratory oxygen principle)
Q:What is catalyst in Science?
A catalyst is a substance that increases the rate of a reaction by decreasing the activation energy (energy required to start the reaction). It does so by creating a new reaction mechanism (the way the reaction happens on a molecular level) that happens more easily and with less energy. For example, a catalyst could attract both reactants, thus bringing them directly together and facilitating the reaction.
Q:Is the catalyst considered a chemical reaction?
The middle school textbook defines that the catalyst itself does not participate in chemical reactions
Q:enzymes and catalyst are....?
A catalyst is a substance that affects the rate of a reaction. It may participate, but cannot be consumed in the reaction. For example, KMnO4 catalyzes the breakdown of H2O2 into H2O and O2. In the end, as much KMnO4 exists as did in the beginning. An enzyme is a biochemical reagent that allows an organism to convert a compound into other compounds. This is part of metabolic processes. For example, maltose (a sugar composed of a chain of two glucose molecules) can be broken down into glucose by the maltase enzyme. Unlike a catalyst, enzymes may or may not be consumed/altered in the metabolic processes.
Q:what is the difference between enzyme and catalyst?
Enzymes and catalysts both affect the rate of a reaction. The difference between catalysts and enzymes is that while catalysts are inorganic compounds, enzymes are largely organic in nature and are bio-catalysts. Even though all known enzymes are catalysts, all catalysts are not enzymes. Moreover, catalysts and enzymes are not consumed in the reactions they catalyze. Catalysts are low molecular weight componds, enzymes are high molecular globular proteins. Catalysts are inorganic, enzymes are organic. Catalyst reaction rates are slower (usually) than enzyme reaction rates. Catalysts are not generally specific - enzymes are VERY specific. Catalysts increase or decrease the rate of a chemical reaction, enzymes are proteins that incrase the rate of chemical reactions & convert the substrate into product. There are 2 types of catalysts - (positive & negative), and the 2 types of enzymes are activation enzymes and inhibitory enzymes. Catalysts are simple inorganic molecules, while enzymes are complex proteins.
Q:describe a biological catalyst?
Biological catalysts work in similar fashion to inorganic catalysts. The lower the activation energy (Delt. G) of the rate limiting step in an SN1 or SN2 reaction. However, they are comprised of biomolecules susceptible to degradation and are quite sensitive to temperature change.
