Question

In this reaction,
2SO2(g) + O2(g) ⇌ 2SO3(g) + Heat

shift equilibrium right
shift equilibrium left
increase the temperature
have no effect

Answer 1

Increasing the temperature will shift the equilibrium to the right, favoring the formation of more SO3(g) while using up some of the reactants. This is known as Le Chatelier's principle, which states that a system at equilibrium will respond to a stress in a way that counteracts that stress. In this case, increasing the temperature is a stress, and the system will respond by absorbing the added heat and producing more product.
