### 7D.7

For 7D.7, why is the reaction endothermic if the reverse rate constant is larger than the forward rate constant?

For this question, you should look at the activation energies. It helps to draw it out. If it takes 39.7kj/mol for the forward reaction and only takes 25.4kj/mol for the reverse reaction, you can determine that the end of the forward reaction has higher energy than the start of the forward reaction, making it endothermic

but if the forward reaction has a higher activation energy, doesn't that mean that it is favored?
