Consider the reaction:
3 H2 (g) + N2 (g) = 2 NH3 (g) ΔH = 91.8 kJ/mol
If this reaction is at equilibrium and the temperature is increased, what will happen to the concentration of H2 and NH3?
A) [H2] decreases; [NH3] increases
B) [H2] increases; [NH3] decreases
C) It cannot be determined from the information given.
D) [H2] increases; [NH3] increases
E) [H2] decreases; [NH3] decreases
