Question

The first order rate constant for the decomposition of CaCO_3 at 700 K is 6.36 10^ -3 s^ -1 and activation energy is 209 kJ mol^ -1 Its rate constant (in s^ -1 ) at 600 K is X 10^ -6 . The value of x is ——. (Nearest integer) [Given R = 8.31 J K^ -1 mol^ -1 ; log 6.36 10^ -3 = –2.19, 10^ -4.79 = 1.62 10^ -5 ]
