#### Solution Preview

The variation of rate constant with temperature can be explained using the Arrhenius relationship

k = A exp(-Ea/RT)

where,

T is the Temperature, meaured in kelvin. As a rule of thumb, a temperature increase of 10Â° causes a the reaction speed to double.

R is the gas constant.The value of the gas constant,R = 8.31JK-1mol-1.

Ea is the ...
