Chapter 9 Q 8 Consider the gas-phase reaction, 2 SO 2 + O 2 <=> 2 SO 3 , for which K p = 2 at a given temperature. If the mixture is analyzed and found to contain 3.1 bar of SO 2 , 0.9 bar of O 2 and 4.1 bar of SO 3 , describe the situation (using one decimal place in your considerations): Student Response Value Correct Answer Feedback 1. Q < K and more reactants will be made to reach equilibrium. 0%
