Problem

The reaction shown below has K= 81.9 at 25°C.

I2(g) + Cl2(g) ⇌ 2 ICl(g)

A flask contains Pi2 = 0.114 atm, PCl2 = 0.102 atm, and PICl = 0.355 atm. Choose the answer that best describes how this mixture will behave.

A) The reaction is at equlibrium, so the concentrations will not vary.

B) The reaction is not at equilibrium and will generate more products.

C) The reaction is not at equilibrium and will generate more reactants.

D) The reaction will not proceed without the addition of a catalyst.

E) The rate constant of the reaction is needed to solve this problem.
