When is the reaction spontaneous?

When is the reaction spontaneous?

Options

  1. AΔG=2.0\Delta G = 2.0
  2. BΔG<0\Delta G < 0
  3. CΔG=0\Delta G = 0
  4. DΔG=1\Delta G = 1

Correct answer

B. ΔG<0\Delta G < 0

Step-by-step solution

For a process to be spontaneous at constant temperature and pressure, the change in Gibbs free energy (\Delta G)mustbenegative.<br><br>IfΔG<0) must be negative.<br><br>If \Delta G < 0, the reaction is spontaneous.

If ΔG=0\Delta G = 0, the reaction is at equilibrium.

If ΔG>0\Delta G > 0, the reaction is non-spontaneous.

Answer: ΔG<0\Delta G < 0
