Show hintHide hint
Think about what determines a reaction's ability to proceed.
Question 2.
What is the condition for spontaneity in terms of Gibbs Energy?
Show hintHide hint
Consider the implications of negative energy for processes.
3Question 3.
What does a negative Gibbs energy imply?
- The process is non-spontaneous.
