Equilibrium Question 790

Question: Consider the expression ΔG=,RT,lnKp+RT,lnQp and indicate the correct statement at equilibrium

Options:

A) ΔG=0,Qp>Kp the equilibrium reaction will shift from left to right

B) ΔG=0,Qp=Kp the equilibrium reaction will shift from left to right

C) ΔG=,Qp<Kp the equilibrium reaction will shift from right to left

D) ΔG<0,Qp>Kp the equilibrium reaction will shift from right to left where Qp and Kp term refer to reaction quotient and equilibrium constant at constant pressure respectively.

Show Answer

Answer:

Correct Answer: B

Solution:

Van’t Hoff reaction isotherm is ΔG=ΔG+RT In Qp When the reaction is in a state of equilibrium ΔG=0 Then ΔG=RT,ln,Qp=RT ln Kp
