According to le chatelier’s principle, a change in pressure affects the chemical equilibrium of the reaction system under what condition? the reactants and the products are in the solid phase. the reactants and the products are in the liquid phase. some of the reactants or the products are in the gaseous phase. some of the reactants or the products are solid, and some are liquid.

Some of the reactants or the products are in the gaseous phase.

Mgo2 is the oxidation state of manganese oxide

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
