Question

Which is an overall third-order reaction?
Would the order be R=[x]2[y]3 or R=[x][y]1, i know which is 1st and 2nd but idk which is 3rd

Answer 1

From what I remember, the overall order of reaction is the sum of the exponents
so for example you have \(\sf R=[a]^c[b]^d\) the overall reaction would be \(\sf c+d\) (sum of the exponents)

Answer 2

hmm i don't think so
it should be like \(\sf R=[x]^2[y]\ or\ R=[x][y]^2\) to have an overall third-order

Answer 3

^_^ just remember the \(\sf \color{blue}{sum}\) of the exponents of the reactants
