Concept explainers
(a)
Interpretation:
A flowchart of process along with degree of freedom analysis needs to be prepared and molar amounts of all species in product to be calculated.
Concept introduction:
Flow chart is diagrammatic representation of the reaction taking place in the reactor:
The calculation of flowchart is based on the relation
It helps us to determine the amount of product formed with respect to the amount of reactant fed to the reactor.
Mole fraction
Here,
(b)
Interpretation:
The amount of heat added or removed from the reactor is to be calculated
Concept introduction:
The amount of heat transferred is calculated as follows:
Based on energy conservation
Here,
Enthalpy of reactant and product depends upon the specific heat and the temperature difference.
(c)
Interpretation:
If the process is considered for biodiesel formation, whether biodiesel is economically viable as compared to petroleum diesel or not needs to be determined.
Concept introduction:
Energy transfer equation,
This equation helps to determine the amount of energy generated in product stream with respect to the energy given to the reactor.
(d)
Interpretation:
For atomic species, the degree of freedomneeds to be calculated.
Concept introduction:
Degree of freedom helps to determine the feasibility of reaction and tells about the number of unknowns in a reaction.
The formula for degree of freedom is given as
Degree of freedom = no. of unknown + no. of chemical reaction − no of independent molecular species − no of independent non-reactive molecular species − no. of equation relating unknown
