Question
Given the following fictitious reaction and reaction rate data, find m, n and p.
A-(aq) + BC(aq) + D+(aq) A(aq) + B(aq) + DC(aq)
General Rate equation:
Relative Rate = k'(A-)m(BC)n(D+)p
Remember that m, n and p should be integers.

Explanation / Answer
m = 3
by doubiling the concentratration of A rate increases three times
n = 1
when doubling the concentration of BC rate just doubled.
p = 2
when concentration of d increases rate increases 2 times
