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

According $LeChatelie{r}^{\prime }sprinciple$ Equilibrium is affected by changes in concentrations, temperature, pressure, and volume. It is not affected by the presence of a catalyst. The presence of a catalyst just helps to achieve the equilibrium at a different pace. It does not affect the amount of a reactant or a product at equilibrium.

Hence the correct answer is option$A$
