Can someone explain how to write the generic rate law for number 7? I keep getting it wrong. Thanks.

Hi there! I'm not sure if we were both given the same numbers for this problem, but I'll just explain it with the ones I was given. For this reaction, I found that reactant A is first-order, reactant B is second-order, and reactant C is zero-order. For the rate law, I wrote that rate = k[A][B]^2 because since A is first order, it's going to have a one as its exponent, and B is going to have 2 because it's second order. I did not include C because it is zero order, with an exponent of 0, which would have turned the whole term into 1. I hope this helps!

From your post it sounds like you know the order of each reactant but are still getting the rate law wrong, so it will just be (Rate=k[A]) with an exponent corresponding to the order of each reactant. However, if the order is 0, you just omit the reactant entirely, and if it is 1, you dont put an exponent.

use brackets and exponents to write the equation that you get from determining the order of each reactant.
