Example

Problem: Consider the gas-phase reaction, 2 SO2 + O2 <=> 2 SO3, for which Kp = 2 at a given temperature. If the mixture is analyzed and found to contain 3.1 bar of SO2, 0.9 bar of O2 and 4.1 bar of SO3, describe the situation (remembering significant figures).

FREE Expert Solution

We are being asked to describe the situation for a system where a reaction: 

2 SO2 + O2 ↔ 2 SO

and given the partial pressures: 3.1 bar of SO2, 0.9 bar of O2 and 4.1 bar of SO3


We will use the reaction quotient, Q, to determine if the chemical reaction would be at equilibrium or not. The formula for Q is:


Q = productsreactants


Depending on if Q is greater than or less than K, our reaction will shift to attain equilibrium by reaching the equilibrium constant K:
