Question 25 of 50 from the Joint Admissions and Matriculation Board (JAMB) Chemistry 2009 Objective paper, with the correct answer and a full explanation.

C(s)+H2O(g) -> H2(g)+CO(g), delta G for the reaction above at 1300K is -43kJ. At this temperature, the reaction is

A. not feasible
B. feasibleCorrect
C. —
D. —

Explanation

Since delta G is negative, the reaction is feasible (spontaneous). A positive delta G means that reaction is not feasible. If delta G equals 0, the reaction is at equilibrium.
