How will the equilibrium of the following reaction be affected if additional nitrogen is added?N2(g) + 3H2(g) ⇌ 2NH3(g)
Correct answer: A. It will be shifted to the right.
- A. It will be shifted to the right.
- B. It will be shifted to the left.
- C. It will be unaffected.
- D. The effect on the equilibrium can not be determined without more information.
- E. Less NH3 will be produced.
Explanation
If N2 is added, the equilibrium will be shifted to the right side as N2 is the reactant. According to Le Chatelier, increasing the concentration of the reactants favour the forward reaction.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.

Which of the following reaction has greater Kp than Kc?
For the following exothermic reaction, a decrease in temperature will shift the equilibrium towards: 2NO(g) + O2 (g) -> 2NO2 (g)
In the reaction, 2SO2 (g) + O2 ⇌ 2SO3 (g) ∆H= -X cal most favorable conditions of temperature and pressure for a greater yield of SO3 are:
The value K for H2(g) + CO2(g) <-> H2O(g) + CO(g) is 1.80 at 1000 C. If 1.0 mole of each H2 and CO2 are placed in 1 litre flask, the final equilibrium concentration of CO at 1000 C will be:
1.8 x 10 -5 is the dissociation constant of:
If 4.6 gm of ethyl alcohol and 6.0 gm of acetic acid is kept at a constant temperature until equilibrium was established, 2.0 gm of unused acetic acid were present. What is the Kc?
