The given reaction is second order with respect to A, first order with respect to B and zero order with respect to C.
3 A(g) + 2 B(g) + C(g) → 2 Y(g) + 2(g)
(a) Write the rate law for the reaction and determine the overall order.

(b) Predict by what factor does the rate of reaction change if each of the following changes occurs.
(i) [A] triples
(ii) [B] doubles
(iii) All reactants concentrations are tripled
