Quick questions on Gibbs free energy and thermodynamic favorability - AP Chemistry Unit 9

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

\Delta H = +60.\ \text{kJ}

and

\Delta S = +150\ \text{J K}^{-1}

. Calculate the temperature above which it is favorable. [2 points]

What is q2?

Show answer

State whether a reaction with

\Delta H > 0

and

\Delta S < 0

can ever be favorable. [1 point]
