 P: 123 this seems a fairly straight forward qn but the ans at the back of the book does not agree with my ans :( we have a rate constant 5e-2 mol/L inital concentration of 1e-3 M calculate concentration after the time elapsed is 5e-3 s my ans is 7.5e-4 but the ans at the back claims it is 2.5e-4 formula i using is the integrated rate law [A] = -kt + [A initial] did i miss something?
 PF Patron HW Helper P: 1,198 The units of your rate constant aren't correct. It should be mole L-1 sec-1. Since it's a zero order reaction, your rate law is correct. Check your calculations.
