Hi,

Given the equation 2A  C, what is the constant of proportionality (k) if C is produced at a rate of 1.0M/hr when 10.0 moles of A are in a 2.0L container.

The first thing I did was to figure out the rate law: R=k[A]^2
However, I am stuck at finding the values of R and [A] in order to solve for k.
Would the value of [A] be 5M?
Also, how would I solve for R? Since the amount of A being used is 2 times the amount of C being produced, would the rate of A being used up be 2.0M/hr? How is this all related to R?

Thanks. All help is very much appreciated!

Proportionality of what to what?

Pardon me, not the constant of proportionality...the rate constant.

So basically just solving for k. k=R/[A]^2
