2021 · 27 Aug · Shift 2 · Q13

JEE MainChemistryChemical Kinetics and Nuclear ChemistryNumerical+4 / −1
The first order rate constant for the decomposition of CaCO3CaCO_3CaCO3​ at 700 K is 6.36 ×\times× 10 −-− 3s −-− 1 and activation energy is 209 kJ mol −-− 1. Its rate constant (in s −-− 1) at 600 K is x ×\times× 10 −-− 6. The value of x is ‾\underline{\hspace{2cm}}​. (Nearest integer) [Given R = 8.31 J K −-− mol −-− 1; log 6.36 ×\times× 10 −-− 3 = −-− 2.19, 10 −-− 4.79 = 1.62 ×\times× 10 −-− 5]
