What is the value of DeltaG if DeltaH= +12.0 kJ, DeltaS= -5.00 kJ/K and T = 290K?

Question

Tell whether this reaction is spontaneous

partial answer: 1XXX

Answer 1

Let's start with equation, ΔG = ΔH - TΔS.

Substituting the values into this equation gives..

ΔG = 12 kJ- (290K *-5.00kJ/K)

ΔG = 1462

Since ΔG is positive, the reaction is not spontaneous.
