Question

I need help with number 45. I already have the answer, but I'm not sure how to get to that point. Please show you're work if you want the full points, thank you.

A 0.1 M NaCl solution would have a pH of 1 2 7 13 What is the hybridization of carbon in C2H4? SP SP2 SP3 SP3d The rate law for a particular reaction is Rate = [A][B]2. If for a particuler run of this reaction, the concentration of B were tripled over what it had been in the previous run but the concentration of A reminded the same, what would be the effect on the rate? would not change would trilpe would decrease ninefold would increase ninefold The dencity oa a material is 2g/cc. what would be the volume in cc of 12 g of this material? 6 24 0.17 14

Explanation / Answer

Rate_i= [A] [B]^(2)

when concentration of A remains same and concentration of B is tripled

Rate_f = [A] [3B]^(2) = 9* [A] [B]^(2) = 9*Rate_i

Correct Answer : D rate would increase ninefold
