Which of the following conditions are not suitable for a spontaneous reaction?
- A \(\Delta H < 0\) and \(\Delta S>0\) at low temperature.
- B \(\Delta H < 0\) and \(\Delta S < 0\) at high temperature.
- C \(\Delta H < 0\) and \(\Delta S < 0\) at low temperature.
- D \(\Delta H>0\) and \(\Delta S>0\) at high temperature.
Answer & Solution
Correct Answer
(B) \(\Delta H < 0\) and \(\Delta S < 0\) at high temperature.
Step-by-step Solution
Detailed explanation
\(\Delta G\) (Gibbs' free energy) must be negative for a spontaneous reaction. Using Gibbs' free energy equation, we can find favourable conditions.…
