For a reaction pA + qB → Products. Rate = K(A)m(B)n. Then
(p+q) = (m+n)
(p+q) ≠(m+n)
(p+q) > (m+n)
(p+q) = (m+n) or (p+q) ≠(m+n) ✔

9 )
In the reaction A + B → Products, the doubling of [A], increases the reaction rate to four times, but doubling of [B] has no effect on the reaction rate. The rate expression is ….
Rate = K (A)^2 ✔
Rate = K (A)
Rate = K (A)^2 (B)^2
Rate = K [A][B]
