Given the reaction orders based on the data given below.

Question

Given the data below for the reaction, 2 A + 2 B + 4 C => D + E + 3 F, the reaction is __________ order in A, ________ order in B, ________ order in C and ________ order overall

Experiment	Initial conc of A, mol/L	Initial conc of B, mol/L	Initial conc of C, mol/L	Initial rate, mol/L.s
1	0.1	0.1	0.2	2 x 10-3
2	0.2	0.3	0.2	1.2 x 10-2
3	0.3	0.1	0.2	6 x 10-3
4	0.4	0.3	0.4	4.8 x 10-2

Answers:

A is first order

B is first order

C is first order

Overall is third order

Answer 1

First order in A (compare exps 1 and 3)

First order in B (compare exps 1 and 2)

First order in C (compare exps 1 and 4)

Overall order is third order (1 + 1 + 1)
