1. For the following reaction at equilibrium, the pressure of the reacting mixture is 0.351 atm at 350 oC. Calculate Kp for this reaction.
MgCO3 (s) ⇌ MgO (s) + CO2 (g)
2. The reaction quotient for a given point in a reaction is measured to be 5.32 x 10-3. If the equilibrium constant for the same reaction is measured to be 2.44 x 10-4, the reaction is predicted to drive to the left and form reactants. TRUE or FALSE?
