7.4 Calculating the Equilibrium Constant
7.3 Reaction Quotient and Equilibrium Constant
A mixture of \(\text{SO}_2(g)\) and \(\text{O}_2(g)\) is sealed in a rigid reaction vessel at a constant temperature. The system reaches equilibrium according to the following equation:
\[ 2\,\text{SO}_2(g) + \text{O}_2(g) \rightleftharpoons 2\,\text{SO}_3(g) \]
At equilibrium, the partial pressures of the gases are \(P_{\text{SO}_2} = 0.20\text{ atm}\), \(P_{\text{O}_2} = 0.10\text{ atm}\), and \(P_{\text{SO}_3} = 0.80\text{ atm}\). What is the value of the equilibrium constant, \(K_p\), for the reaction at this temperature?
