Entropy ­ Answers
1. In an endothermic reaction, the chemicals gain energy and the surroundings lose an equal quantity of energy. Clearly
the feasibility of process or change cannot solely depend on the enthalpy change and in order to explain further you
need to consider the concept of ENTROPY and…

11. Spontaneous endothermic reactions:
When solid ammonium carbonate is added to pure ethanoic acid, bubbles of gas are rapidly produced. This
appears to be a violent reaction, but the temperature actually falls during it. Even though the reaction is
endothermic, entropy of the system increases because a gas is produced.…
