2short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.

What is q1?

Show answer

A reaction has forward

E_a = 90.\ \text{kJ mol}^{-1}

and

\Delta H = -30.\ \text{kJ mol}^{-1}

. Calculate the reverse activation energy. [2 points]

What is q2?

Show answer

Explain why a catalyst changes the activation energy but not the enthalpy of reaction. [2 points]
