Question

For the chemical reaction : $3X\left(g\right)+Y\left(g\right)\rightleftharpoons X_{3}Y\left(g\right)$ the amount of $X_{2}Y$ at equilibrium is affected by-

• A. Temperature and pressure.
• B. Temperature only.
• C. By adding X(g) and Y(g).
• D. By adding catalyst.

Answer 1

Answer: (A), (C)

The correct options are
A Temperature and pressure.
C By adding X(g) and Y(g).

The equilibrium of a reaction is affected when the concentration of reactants and products are changed. The reaction for which the value of $\Delta n$ is non zero is affected by the change in pressure. The reaction can be either exothermic or endothermic. Such reaction is affected by temperature change.
