Chemical kinetics asks how fast reactions occur and which molecular steps control that speed. Concentration, temperature and catalysts can change the observed rate.
A catalyst changes the pathway and can lower the activation barrier; it does not change the equilibrium constant.

Choose a concrete case linked to Reaction rates. Write down the known information, what you are trying to find, and the units. Then state the rule, model or trend you will use. If a calculation is involved, keep the units visible at every line; if it is conceptual, state what changes and what remains fixed.
A strong answer contains four things: the starting situation, the variable that changes, the direction or numerical result, and one check. The check can be a unit, an order of magnitude, a limiting case or a comparison with a familiar example.
