For the reaction A+2B > 2C, the rate of reaction is 1.76 x 10^-5Ms^{^-1} at the time and [A]₀= 0.3580M.
a.What is the rate of formation of C?
b. What will [A] be 1.00 minutes later?
c. What is the disappearance rate of A after 1 min

I actually think I know a.  My answer for rate of formation of C is 3.52x10^-5Ms^-1.
Question b Im not really sure how to answer.  Im thinking that I take the initial concentration of A and multiply it by the overall rate of the reaction multiplied by 60 (for 60 seconds) but Im not sure if thats correct.  Once I figure out how to do b I think I can do c.  Any help would be greatly appreciated.

b.
A + 2B  2C

[A]_t = [A]₀e^-k*t
ln[A]_t=[A]₀-kt

Get k from the first load of rubbish and substitute, t will be 60 and then that should give you an answer when all is done.
