The specific rate constant(k) of a first order reaction depends on the:
Time
Concentration of reactant
Concentration of product
Temperature
We know that on increasing the temperature, the rate of the reaction or rate constant increases.
Generally, on 10oC rise in temperature, the rate constant nearly doubles.
Temperature Coefficient: It is the ratio of two rate constants. Thus, mathematically it is given as:
The specific rate constant(k) of a first-order reaction depends on temperature.
Therefore, option(4) is correct
