Question

Given the equation representing a system at equilibrium:
N2(g) + 3H2(g)<==>2NH3(g) + energyWhich changes occur when the temperature of this system is decreased?
(1) The concentration of H2(g) increases and the concentration of N2(g) increases.
(2) The concentration of H2(g) decreases and the concentration of N2(g) increases.
(3) The concentration of H2(g) decreases and the concentration of NH3(g) decreases.
(4) The concentration of H2(g) decreases and the concentration of NH3(g) increases.

Answer 1

N2(g) + 3H2(g)<==>2NH3(g) + energy, the changes that occur when the temperature of this system is decreased is that concentration of H2(g) decreases and the concentration of NH3(g) increases. The answer is number 4. The rest of the choices do not answer the question above.

Answer 2

When the temperature is decreased, the concentration of H2(g) decreases and the concentration of NH3(g) increases.

What is equilibrium?

The term equilibrium refers to the point when the rate of forward reaction is equal to the rate of reverse reaction. In that case, the reaction has attained a dynamic equilibrium.

Now, when the temperature is decreased, the concentration of H2(g) decreases and the concentration of NH3(g) increases.
