For the reaction, aA + bB → cC + dD , the plot of log   k v/s 1   T is given below: The temperature at which the rate constant of the reaction is 10 - 4   s - 1 is _____ K . (Rounded-off to the nearest integer) [Given : The rat5e constant of the reaction is 10 - 5   s - 1 at 500   K .]

Correct answer

0

Step-by-step solution

log   k = log   A - Ea 2 . 303 RT Slope =   Ea   2 . 303 R = 10 , 000 log k 2   k 1 = Ea 2 . 303 R 1   T 1 - 1   T 2 log 10 - 4 10 - 5 = 10 , 000 1 500 - 1   T 2 log 10 - 4 10 - 5 = 10 , 000 1 500 - 1   T 2 T 2 = 526 . 31 ≃ 526   K Hence answer is 526
