how would the equilibrium change if the temperature were increased in SO2(g)+NO2(g) --> SO3(g) +heat?

Answer:
D. The amount of nitrogen dioxide and sulfur dioxide would increase.
Explanation:
Because the reaction is exothermic, heat is a product. According to Le Chaetelier's Principle, a system in equilibrium will adjust itself so as to relieve any stress placed upon it. If the temperature of the system increases, there are more products, and therefore the system is no longer at equilibrium. Thus, it will shift to favor the reactant side of the equation, where sulfur dioxide and nitrogen dioxide are located. This makes the answer D.
Edit: Brainly thinks that the correct spelling of 'Le Chaetelier' is a bad word so that's why it is spelled wrong lol.
