Look at the equation for a reversible reaction.
2SO2(g)+O2(g)⇌2SO3(g)ΔH=−197 kJ mol−1 2\text{SO}_2(\text{g}) + \text{O}_2(\text{g}) \rightleftharpoons 2\text{SO}_3(\text{g}) \quad \Delta H = -197\text{ kJ mol}^{-1} 2SO2(g)+O2(g)⇌2SO3(g)ΔH=−197 kJ mol−1The reversible reaction forms a dynamic equilibrium in a sealed container.
Which of the following would move the position of equilibrium to the right?
Decreasing the pressure and increasing the temperature.
Increasing the pressure and decreasing the temperature.
Increasing the pressure and increasing the temperature.
Decreasing the pressure and using a catalyst.
