The rate of formation of a product depends on the the concentrations of the reactants in a variable way.
If two products, call them A and B react together to form product C, a general equation for the formation of C has the form:
rate = k*[A]^m * [B]^n
Where the symbol [ ] is the concentration of each compound.
Then, plus the concentrations of compounds A and B you need k, m and n.
Normally you run controled trials in lab which permit to calculate k, m and n .
Here the data obtained in the lab are:
Trial [A] [B] Rate
(M)
(M) (M/s)
1 0.50
0.010 3.0×10−3
2 0.50 0.020 6.0×10−3
3 1.00
0 .010 1.2×10−2
