Determine the molecularity and write the rate law for each of the following elementary steps:(a) $\mathrm{X} \longrightarrow$ products(b) $\mathrm{X}+\mathrm{Y} \longrightarrow$ products(c) $\mathrm{X}+\mathrm{Y}+\mathrm{Z} \longrightarrow$ products(d) $\mathrm{X}+\mathrm{X} \longrightarrow$ products(e) $\mathrm{X}+2 \mathrm{Y} \longrightarrow$ products

(a) unimolecular, rate $=k[\mathrm{X}]$(b) bimolecular, rate $=k[\mathrm{X}][\mathrm{Y}]$(c) termolecular, rate $=k[\mathrm{X}][\mathrm{Y}][\mathrm{Z}]$(d) bimolecular, rate $=k[\mathrm{X}]^{2}$(e) termolecular, rate $=k[\mathrm{X}][\mathrm{Y}]^{2}$

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 this question, they want us to determine the molecular polarity and the rate lof. Okay, so the same molecular already first. So right here and a we see that we have one reactant. This means that it's a unique molecular, its unique molecular reaction. Now, when we look at B, we see that there's two reacting. So this is by molecular, you see that this is three reacting. So it's her molecular, and we see that this is too. So this is also by molecular and we see that this is all this has three, actually, because there is too wise here and there's one act. So this is also turn molecular Alyssa gorilla. So the rail all have similar uh, they all look similar. So it's always rate. Is he going to k times that by something? Right. So lets you This is a union likelier. So we have one X but so that is your rate law for a This is by Milica So we have. Rape is equal to K times by X times that by concentration of lie this is terminal killers. We have rate. Does he go to K X times about Why times that by Z now for this one, This is by molecular. But this is different from the bio molecular and part B. Why? Because we have two X. This means that we're i k concentration of x square as I answer. And now for B, we have rates physical to K times about concentration of X times about a concentration of why square, right? Because we have to wise here.
