In probability theory, the conditional probability of an event A given that another event B has occurred is defined as the probability of A given B, written as P(A|B). It is a function of the probability of B, the probability of A given B, and the probability of B.
In chemistry, kinetics is the study of the rates of chemical reactions. The rate of a reaction is the change in concentration of a reactant over time. The rate of reaction is dependent on the concentration of the reactants, temperature, and the activation energy of the reaction.

Okay, so for a its activation energy and the catalyst actually decreases theatric ation energy of a reaction to make the reaction faster for B, we have reaction mechanism and a catalyst changes. Do you reaction mechanism, the reaction mechanism to an alternate routes. So what I mean by that is let's say we have this reaction with a certain amount of activation energy by here, right? So what happens when a catalyst is added is that informs another alternate route with a lower activation energy. Right. So this forms an alternate route right here. Any increases to you? Rate of reaction now for part C, its entropy of reaction. So a catalyst does not affect so catalyst does not effect in therapy of reaction. And then for D and E, it says the rate of forward and reverse step. So it's just d must be. So a catalyst increases. Do you rate of both forward and reverse reaction steps. And why is that? Well, if we look appear, we see that the alternate route it would go from this side. It decreases Thea activation energy, which means I increases the reaction rate. But if we were to go from right two left, we see that also decreases the activation energy. This increases. Do you reaction speed
