Question

Which of the following changes would cause the reaction below to shift in the forward direction to reestablish equilibrium? 2 NBr; (g) = N2 (g) + 3 Brz (9) A) adding a catalyst. II B) adding Ar (9). C) increasing the total volume of the container. D) adding N2.

Answer 1

adding N2 will shift the reaction backward to attain equilibrium.

increase of volume shift toward more mole present.

thus, increase in volume will shift forward reaction.
