Question: The following two liquid-phase reactions occur in parallel within a reaction system: A --> B (1) A-->C (2) Reaction 1 has the rate law

The following two liquid-phase reactions occur in parallel within a reaction system:

The following two liquid-phase reactions occur in parallel within a reaction system: A --> B (1) A-->C (2) Reaction 1 has the rate law - = kCA and reaction 2 has the rate law -A2 = K2CA. The activation energy for reaction 1 is 35.7 kJ/mol and the activation energy for reaction 2 is 17.8 kJ/mol. Assume that the Arrhenius equation pre-exponential factors are constant over temperature. If B is the desired product, which of the following reaction conditions should be used to maximize the selectivity of B?
