When a cylinder of nitrogen is left standing in the sun, the temperature of the
gas reaches 42 oC. The cylinder has a pressure of 12 atm and contains 128
grams of nitrogen (N2). What is the volume inside the cylinder?

idk what the question is about

a. energy is absorbed in the reaction.

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.
