Question
Questions 35-36 refer to the experiment described below.
H2 gas and N2 gas were placed in a rigid vessel and allowed to reach equilibrium in the presence of a catalyst according to the following equation.
3 H2(g) + N2(g) ⇄ 2 NH3(g) ΔH° = -92 kJ/molrxn
The diagram below shows how the concentrations of H2, N2, and NH3 in this system changed over time.
[VISUAL]
More NH3 gas is added to the system at time t2 while the temperature is held constant. Which of the following will most likely occur?
A.
The value of the equilibrium constant will increase.
B.
The value of the equilibrium constant will decrease.
C.
The total pressure in the container will decrease.
D.✓ Correct
The amount of N2 will increase.
E.
The amount of H2 will decrease.
