Problem

In an energy diagram for the reaction

A \rightarrow B

, the reactants are at 65 kJ and the transition state is at 210 kJ, both relative to the same baseline. What is the activation energy,

E_a

, for the forward reaction? a)

275\ \text{kJ}

65\ \text{kJ}

145\ \text{kJ}

210\ \text{kJ}
