Concept explainers
(a)
Interpretation:
The rate of heat removal to produce
Concept introduction:
According to the Hess’s law, the total enthalpy for a reaction is the sum of all the changes in the multiple steps of the reaction. According to this law, enthalpy is a state function.
Specific heat capacity
Here,
Change in specific enthalpy
The rate of heat transfer is calculated as:
(b)
Interpretation:
An expression for the rate of heat removal is to be written in terms of the heat capacities and latent heats of
