Question

For a chemical reaction $3X\left(g\right)+Y\left(g\right)\leftrightharpoons X_{3}Y\left(g\right),$ 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

According to van't hoff isotherm,
Equilibirum constant is dependent of pressure. Change of equilibrium constant leads to change in the amount of products and reactants.

According to Le Chatlier principle,
Increase of pressure at equilibirium shifts the equilibrium to the side that has less number of products. In the above reaction, it shifts to the product side and will lead to increase in the amount of $X_{3}Y$
