Which is necessarily true for a spontaneous process

The rate of a reaction is independent of its spontaneity, and instead depends on the chemical kinetics of the reaction. Every reactant in a spontaneous process has a tendency to form the corresponding product. This tendency is related to stability. An endergonic reaction also called a nonspontaneous reaction or an unfavorable reaction is a chemical reaction in which the standard change in free energy is positive, and energy is absorbed.

The total amount of energy is a loss it takes more energy to start the reaction than what is gotten out of it so the total energy is a negative net result. Endergonic reactions can also be pushed by coupling them to another reaction, which is strongly exergonic, through a shared intermediate.

Therefore, flow of heat from a cold body to a hot body is a non-spontaneous process as it requires external work as per Clausius. In chemistry, a spontaneous processes is one that occurs without the addition of external energy. A spontaneous process may take place quickly or slowly, because spontaneity is not related to kinetics or reaction rate. Terms in this set 37 Which statement about spontaneous and nonspontaneous processes is correct?

Spontaneous processes are favored by a decrease in mc An enthalpy diagram plots information about a chemical reaction such as the starting energy level, how much energy needs to be added to activate the reaction, and the ending energy.

An enthalpy diagram is graphed with the enthalpy on the y-axis and the time, or reaction progress, on the x-axis.

Your answer will be in the unit of energy Joules J.
