Question

A reaction in which A, B, and C react to form products is second order in A, zero order in B, and one-half order C.

a) Write the specific rate law for the reaction.

b) What is the overall order of the reaction?

c) By what factor does the reaction rate change if (A) is doubled (all other concentrations are held constant)?

d) By what factor does the reaction rate change if (B) is doubled (all other cocentrations are held constant)?

e) By what factor does the reaction rate change if (C) is doubled (all other concentrations are held constant)?

f) By what factor does the reaction rate change if the concentrations of all three reactants are doubled?

Explanation / Answer

A ) rate = k[A]^2[B]^0[C]^1/2

B) Overall orderof reaction = 2+0+1/2 = 2.5

C) as ordrer w. r. t A = 2 .so that reaction rate increases by 4 times.

d) as ordrer w. r. t B = 0 .so that reaction rate do not changes.

e) as ordrer w. r. t C = 0.5 .so that reaction rate increases by 1.414 times.

f) total order = 2.5 if we double rate constant is increased by 2^2.5 times = 5.67
