Each with a concentration of 0.0100M . The following table shows the concentrations of the gases at equilibrium at a particular temperature.
[A]eq --> 0.01800
If the experiment is repeated at a higher temperature at which Kc is smaller, which of the following best describes the effect of the temperature change on the concentrations of the gases at equilibrium?
A)There will be a decrease in [A]eq that will be two times the decrease in [B]eq because A and B react in a 2-to-1 ratio.
B) [A]eq and [B]eq will remain constant, but [C]eq will increase because Kc decreased.
C) [A]eq , [B]eq , and [C]eq will all increase because Kc decreased.
D)There will be a increase in [A]eq that will be two times the decrease in [B]eq because A and B react in a 2-to-1 ratio.
If Kc got smaller, then the equilibrium must shift to the reagents. This means that C will decrease and both A and B will increase. The increase in A would be two times the increase of B because they react in 2-to-1-ratio. None of the above answers are right.
