The rate of entropy change:
The rate of entropy change of the working fluid during the heat addition process is 3 kW/K
What is the Carnot cycle?
- The Carnot Cycle is a thermodynamic cycle made up of reversible isothermal expansion, adiabatic expansion, isothermal compression, and adiabatic compression processes in succession.
- The ratio of the heat absorbed to the temperature at which the heat was absorbed determines the change in entropy.
The entropy of a system:
The rate of heat addition is expressed as,
Q =
The entropy of a system is a measure of how disorderly a system is getting. The rate of entropy generation during heat addition is,
Calculation:
<u>Given:</u>
= 400K
= 1600K
W = 3600 kW
Put all the values in the above equation, and we get,
=
= 3 kW/K

Explanation:
Sodium hydroxide completely ionizes in water to produce sodium ions and hydroxide ions. Hydroxide ions are in excess and neutralize all acetic acid added by the following ionic equation:
The mixture would contain
of
and
of
if undergoes no hydrolysis; the solution is of volume
after the mixing. The two species would thus be of concentration
and
, respectively.
Construct a RICE table for the hydrolysis of under a basic aqueous environment (with a negligible hydronium concentration.)
The question supplied the <em>acid</em> dissociation constant for acetic acid
; however, calculating the hydrolysis equilibrium taking place in this basic mixture requires the <em>base</em> dissociation constant
for its conjugate base,
. The following relationship relates the two quantities:
... where the water self-ionization constant under standard conditions. Thus
