Question

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

• A. temperature and pressure
• B. temperature only
• C. pressure only
• D. temperature, pressure and catalyst

Answer 1

The correct option is A temperature and pressure

The given reaction will be exothermic in nature due to the formation of three X - Y bonds from the gaseous atoms. The reaction is also accompanied with the decrease in the gaseous species. Hence, the reaction will be affected by both temperature and pressure. The use of catalyst does not affect the equilibrium concentrations of the species in the chemical reaction.
