In any chemical reaction, the total amount of mass and ___ remains constant.

In a chemical reaction, if the total enthalpies of reactants and products are H_(R) and H_(P) respectively then H_(P) gt H_(R) for ______ reaction and H_(R) gt H_(P) for _____ reaction.

In any unimolecular reaction-

Why does the total energy of an isolated system remains constant?

(i) What do you mean by heat of reaction at constannt volume and heat of reaction at constant pressure? (ii) Establish the relation DeltaH=DeltaU=DeltanRT for a chemical reaction in gaseous state.

In any nuclear reaction - (A) The total number of protons and neutrons remains same before and after the reaction. (B) Increase or decrease in the number of protons is equal to the decrease or increase in the number of neutrons. (C) Kinetic energy of the incident particle is approximately 8 MeV or its equivalent. (D) Some energy is released if total mass is reduced.

Chemical reaction require energy for

Give chemical reaction of dihydrogen with

A chemical reaction was carried out at 300 K and 280 K. The rate constants were found to be k_1 and k_2 respectively. Then

Show that the total energy of ann isolated system always remains constant.
