Question

NO(g) + CO2(g) <¡X> NO2(g) + CO (g) ƒ´H¢X = ¡V100 kJ

Which of the following will favor the forward reaction?Why?

A) add NO B) remove NO2
C) decrease the volume of the container
D) raise the temperature E) add CO

Answer 1

Adding NO will favor products. Le Chatelier's Principle.
Removing NO2 will favor products. Le Chatelier's Principle.
decreasing volume of the container will have no effect since the number of moles on the left is the same as the number of moles on the right.
Your post isn't clear as to the sign of delta H, or if, in fact, it is delta H at all; therefore, I can't do D.
Adding CO will favor the reactants. Le Chatelier's Principle.
