The following reaction has a Keq = 195 at 1000 K. + CH4 (g) CO (g) + 3H2(g) → H₂O(g) If a vessel is filled with these gases such that the initial concentrations are [CO] = 0.036 M, [H₂] = 0.045 M, [H₂O] = 0.020 M, and [CH4] = 0.032 M, in which direction will a reaction occur and why? Towards products because Q = 0.38. Towards reactants because Q = 0.24. Towards products because Q = 4.1. Towards products because Q = 61. Neither direction; it is at equilibrium.

Consider the quilibrium reaction between X and Y, as shown below: X=Y AG The reaction is started with 10 mmol of X; no Y is initially present. After 48 hours, analysis reveals the presence of 10 mmol of X and 0 mmol of Y. Which is the most likely explanation? = −1 - 45 kJ mol X and Y have reached equilibrium concentrations. An enzyme has shifted the equilibrium toward X. Formation of Y is kinetically slow; equilibrium has not been reached by 48 hours. Formation of Y is thermodynamically unfavorable. Two of the above explanations are reasonable.
