N 2( g) +3H 2( g) ∼ NH 3( g) + energy Imagine a cylinder containing nitrogen gas (N 2 ), hydrogen gas (H 2 ), and ammonia gas (NH 3 ). The chemicals in the cylinder are in a state of chemical equilibrium according to the above equation. Why would compressing the system with a piston cause the amount of ammonia to increase and the amounts of nitrooen and b. irogen gas to decrease? (A-) A shift of the equilibrium to the right would increase the number of B- Shifting the equilibrium to the right will cause a release of energy, C- Compressing a gas reduces its pressure because it reduces the amount of collisions. collisions. D- Reducing the number of molecules helps reduce the pressure of the system.
