If the Equilibrium Constant for the Following Reaction Is Kc

Question 24

Multiple Choice

If the equilibrium constant for the following reaction is Kc = 1 x 102
2 C2H6(g) + 7 O2(g) If the equilibrium constant for the following reaction is K<sub>c</sub> = 1 x 10<sup>2</sup> 2 C<sub>2</sub>H<sub>6</sub>(g)  + 7 O<sub>2</sub>(g)    4 CO<sub>2</sub>(g)  + 6 H<sub>2</sub>O(g)  And all the concentrations were initially 0.10 M, we can predict that the reaction A)  is at equilibrium initially. B)  must shift from left to right to reach equilibrium. C)  must shift from right to left to reach equilibrium. D)  cannot reach equilibrium. E)  cannot be determined unless we have the information necessary to calculate Q<sub>c</sub> for the reaction. 4 CO2(g) + 6 H2O(g)
