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! Said they were going to be talking about the units of the rate constant for different types of reactions. So for a zero order reaction, the Ray LA was said, play be the rate is equal to the rate constant. Okay, the rate is constant. So our rate is in molar ity for second. So that means that the very constant also has to be in molar ity per second. Very constant is the rate itself, because the rate does not change. So what about ah first order reaction in a first order reaction? The rate is equal to great constant times, the concentration of the reactant. So our rate is in polarity per second, and then our concentration of the reactant isn't polarity. So the units of the very constant have to be the inverse of seconds or one over us. Now, let's talk about a second order reaction. So in a second order reaction, the rate is equal to the rate constant times to react in squared. So the rates has given me similarity per second and then the concentration squared, so that would be in polarity squared. So if we want but to have very similarities per second, we would need one over polarity time. Seconds. So there we go. By knowing the rate law, we can figure out the units of the rate constant. We can also, if we know the units of the rate constant, we can easily determine if it's zero order first water or second or
