Characteristics of a catalyst1. It must not be consumed in the reaction. The total mass of the catalyst before and after the reaction must be the same.2. It does not change the equilibrium constant. It only speeds up the rate of approaching equilibrium.

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.

Hello. So did they were going to be talking about catalysts. So what exactly is a catalyst and what does it do? Well, catalysts are great because they lower the activation energy of ah reaction. However, they are not used up in the reaction. Like, say, we have something, and it's reacting with the catalyst and the catalyst. Converts say A into B and C so that catalyst broke apart A and two B and C. However, it's on both sides. So it did. It didn't disappear, didn't get used up. The amount of catalyst stays the same. It's regenerated so that it can be used further. That's what's so great about it. You don't have to worry about running out of catalyst. So another thing about catalysts as they change the activation energy. But that does not mean they change the equilibrium. So if we draw the potential energy versus reaction progress say this was the original reaction. What a callous does is that lowers the activation energy, so there's going to be a change the activation energy. But there's not going to be any change in the and in the temple P or free energy change. So the equilibrium will stay the same. It's just that it's easier to get the reaction started. We're only changing the activation energy, not that equilibrium itself.
