consider a gas at stp in a container of 22.4 l. if you apply the ideal gas law, what is the approximate value of n?

1

8.31

224

0.5

the answer is either b or c

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
