This question has Statement I and Statement It. Of the four choices given after the Statements, choose the one that best describes the two Statements
Statement - I: Equilibrium constant` K = k_f /k_b`. With increase of temperature, `k_f` and `k_b`, change by the same amount, hence K remains constant.
Statement - II : The increase of temperature of a reaction lowers its activation energy. Hence, both forward and backward reaction become faster to the same extent.

Options

A. Statement - I is true, Statement - II is true,
Statement - II is a correct explanation of Statement - I
B. Statement - I is true, Statement - II ts true,
Statement - II is not a correct explanation of Statement I.
C. Statement - l is true, Statement- Il is false.
D. Statement -I is false, Statement- II is true
