During the kinetic study of the reaction, 2 A + B → C + D , following results were obtained Run [ A ] / m o l L - 1 [ B ] / m o l L - 1 Initial rate of formation of D / m o l L - 1 m i n - 1 I 0.1 0.1 6.0 × 1 0 - 3 II 0.3 0.2 7.2 × 1 0 - 2 III 0.3 0.4 2.88 × 1 0 - 1 IV 0.4 0.1 2.40 × 1 0 - 2 Based on the above data which one of the following is correct?
Options
- Ar a t e = k [ A ] [ B ] 2
- Br a t e = k [ A ] 2 [ B ]
- Cr a t e = k [ A ] [ B ]
- Dr a t e = k [ A ] 2 [ B ] 2
Correct answer
A. r a t e = k [ A ] [ B ] 2
Step-by-step solution
2 A + B → C + D Let r a t e = K [ A ] m [ B ] n To get m- value divide (IV) by I and on solving m = 1 Similarly, to get n devide (III) by (II) and on solving n = 2 Hence R a t e = K [ A ] 1 [ B ] 2
