The integrated rate equation for first order reaction, A → product, is
Options
- Ak = 1 t l n A t A 0
- Bk = 2303 t + l o g 10 A 0 A t
- Ck = 1 t l n A 1 A 0 .
- Dk = 2303 t l o g 10 A 0 A t
Correct answer
C. k = 1 t l n A 1 A 0 .
Step-by-step solution
The integrated rate equation for first order Reaction, A → product is k = 1 t I n A t A 0 . For 1 st order reactions, R → P Rate = - d R d t = k · R On integrating this equation, we get In R = - k t + l . . . i At t = 0 , R = R 0 = - k × 0 + l In R 0 = l Substituting the value of l in (i) and on rearrangement, we get In R = - k t + I n R 0 And, k = 1 t I n R 0 R
