Question

Consider the following system at equilibrium where delta Ho = 198 kJ, and Kc = 2.90E-2, at 1.15E+3 K. 2SO3(g) rightarrow 2SO2(g) + O2(g) If the VOLUME of the equilibrium system is suddenly decreased at constant temperature: the value of Kc increases. decreases. remains the same. the value of Qc is greater than Kc. is equal to Kc. is less than Kc. the reaction must: run in the forward direction to restablish equilibrium. run in the reverse direction to restablish equilibrium. remain the same. It is already at equilibrium. the number of moles of O2 will: increase. decrease. remain the same.
