Q:What is the direction of the chemistry of the material chemistry?
Generally in the chemical plant to do engineering design engineers, the past few years, science and engineering graduates generally do not worry about work.
Q:What progress has chemistry brought to our life?
Q:What is a catalyst and what is it do?
A catalyst is a substance that increases the rate of a chemical reaction.
Q:What is a chemical catalyst?
A substance that participates in chemical reactions but does not change the quality and chemical properties. It can change the reactant activation energy, speed up or slow down the reaction rate.
Q:What are the catalysts?
The catalyst is a substance that can change the rate of the reaction without changing the standard of the reaction Gibbs free, according to the definition of the International Pure and Applied Chemistry (IUPAC) in 1981, Enthalpy change. This action is called catalysis. The reaction involving the catalyst is a catalytic reaction. The catalyst will induce a chemical reaction to change, causing the chemical reaction to become faster or slower or to undergo a chemical reaction at a lower temperature The catalyst is also known as a catalyst in industry, and the composition, chemical properties and quality of the catalyst itself do not change before and after the reaction;
Q:Why can the catalyst change the chemical reaction rate?
Want to write a good article do not reach out.
Q:What is catalyst in Science?
Like everyone told you, catalysts increases the rate of reaction without being consumed. An easy example to think of is mixing natural gas with air --(CH4 + O2). The minute you mix them they are reacting , releasing CO2 as a byproduct and H2O. But they are reacting very slow. But take a match to that slow reaction and it instantaneously reacts with an explosion. In this case the match was the catalyst. It sped up the reaction without adding anything to the reaction or being consumed
Q:Chemistry why the catalyst can be equal to speed up the positive reaction rate
Since the catalyst only changes the activation energy and the amount of reactivity can be reduced, the amount of reaction energy is also reduced. Therefore, a positive catalyst is also a good catalyst for its reaction. Speed up the same multiple.
Q:Hydrogen and oxygen in the role of the catalyst can do the chemical formula of aviation fuel?
You two yeah? Meaning that hydrogen is ignited in oxygen to release energy to push the rocket forward, as the catalyst for those who love,
Q:what is a fuel catalyst?
