nh2co2nh4(s) undergoes the following reaction at 450 k to produce a system which reaches equilibrium: nh2co2nh4(s) ⇌2nh3(g) + co2(g) the total pressure in the closed container under these conditions is found to be 0.843 atm. calculate a value for the equilibrium constant, kp.

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.
