Problem

Two reactions (I)

A \to \text{Products}

(II)

B \to \text{Products}

follow first order kinetics. The rate of the reaction (I) is doubled when temperature is raised from

300 \text{ K}

310 \text{ K}

. The half-life for this reaction at

310 \text{ K}

is 30 minute. At the same temperature

B

decomposes twice as fast as

A

. If the energy of activation for the reaction (II) is half that of reaction (I) calculate the rate constant of reaction (II) at

300 \text{ K}
