Question
For the reaction \[ 2A(g) + B(s) \rightleftharpoons C(g) + D(g) \] at 700 °C, the equilibrium constant \( K_C \) is 0.692. 0.310 moles of A and 0.310 moles of B are placed in a 1.00-L closed container, heated to 700 °C and allowed to reach equilibrium. What is the concentration of C once equilibrium is established? - 0.0900 M (Your answer) - 0.194 M - 0.141 M - 0.0704 M - 0.0968 M (Correct answer)
