Q3. X(g) + 3Y(g) → 2Z(g), ΔH = +ve. If the reaction above takes place at room temperature, the ΔG will be
Anegative
Bzero
Cpositive
Dindeterminate
Correct Answer: C
Using ΔG = ΔH - TΔS. The reaction goes from 4 moles of gas to 2 moles, so ΔS is negative (decrease in disorder). ΔH is positive (endothermic). Therefore ΔG = (+) - T(-) = positive + positive = positive. At room temperature, ΔG > 0 means the reaction is non-spontaneous.
