Solution: Given the equilibrium constant and initial concentrations in a reaction, predict the direction the reaction will proceed The equilibrium constant is equal to 5.00 at 1300 K for the reaction:2 SO 2 (g) + O 2 (g) ⇌ 2 SO 3 (g). If initial concentrations are [SO 2] = 1.20 M, [O 2] = 0.45 M, and [SO 3] = 1.80 M, the system isA) not at equilibrium and will remain in an unequilibrated state.B) at equilibrium.C) not at equilibrium and will shift to the left to achieve an equilibrium state.D) not at equilibrium and wil shift to the right to achieve an equilibrium state

Problem

Given the equilibrium constant and initial concentrations in a reaction, predict the direction the reaction will proceed

 

The equilibrium constant is equal to 5.00 at 1300 K for the reaction:

2 SO (g) + O (g) ⇌ 2 SO (g). If initial concentrations are [SO 2] = 1.20 M, [O 2] = 0.45 M, and [SO 3] = 1.80 M, the system is

A) not at equilibrium and will remain in an unequilibrated state.

B) at equilibrium.

C) not at equilibrium and will shift to the left to achieve an equilibrium state.

D) not at equilibrium and wil shift to the right to achieve an equilibrium state
