Consider the reaction: 2no(g)+o2(g)→2no2(g)estimate î”g∘ for this reaction at each temperature and predict whether or not the reaction will be spontaneous. (assume that î”h∘ and î”s∘ do not change too much within the given temperature range.)a) 298 kb) 723 kc) 842 k

Answer:

a. energy is absorbed in the reaction.

explanation:

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

Electrons are emitted

Qrepresents joules in the formula

Answer    "a salt" would be the best answerexplanationsalts can be defined as ionic compounds that are neither acids nor bases. nacl is an example of a salt, and its ionic.an enzyme is an organic compound which is covalently bonded, not ionically bonded.acids are generally held together by covalent bondsan element does not need any bonds to exist
