Reactant a can participate in both of these reactions: 1) a + b es002-1. Jpg c + d es002-2. Jpggrxn = –15. 6 kj 2) a + e es002-3. Jpg f + g es002-4. Jpggrxn = –20. 5 kj reaction 1 has a much higher rate than reaction 2 under the same reaction conditions. Explain this observation in terms of activation energy.
