When a system is endothermic, where does the heat end up, in the reactants or the products?
Homework Answers
Endothermic means heat energy is taken up during the reaction process. This means the reactants needed energy to match with the energy level of the products and the energy which is conserved (though the form of energy changes from heat to potential energy) thus added ends up in the products when the reactants convert to products.
Comment if still any doubt.

Select the statement that correctly describes an endothermic process. a) Heat is lost by the system, but work is done on the system. b) The enthalpy change for the process is negative. c) Heat is released by the system, to the surroundings. d) The temperature change of the products is greater than that of the reactants. e) The enthalpy of the products is higher than that of the reactants.

Understanding the definitions of heat and work A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1 atm. The cylinder is also submerged in a large insulated water bath. (See sketch at night.) From previous experiments, this chemical reaction is known to absorb 239. LJ of energy. The temperature...
