Interpretation & Concept Introduction:
a) The fuel values of liquid diethyl ether and methyl propyl ether based on the thermochemical data in Appendix 4.
b) Which has higher fuel values?

Answer to Problem 19.88QA
Solution:
a) Fuel value of liquid diethyl ether is
b) Methyl propyl ether has the higher fuel value than diethyl ether.
Explanation of Solution
1) Concept:
To calculate the fuel value of the compound, we need to use the heat of combustion of fuel and molar mass. First we will write the combustion reaction of liquid diethyl ether and methyl propyl ether. Then we will calculate the
2) Formula:
i)
ii)
3) Given:
i)
ii)
iii)
iv)
v)
vi)
vii)
4) Calculations:
Write the balanced combustion reaction of liquid diethyl ether.
Calculate the
If we divide the absolute value of
The fuel value of liquid diethyl ether is
Write the balanced combustion reaction of methyl propyl ether.
Calculate the
If we divide the absolute value of
The fuel value of methyl propyl ether is
The fuel value of methyl propyl ether is higher than liquid diethyl ether.
The fuel value is calculated from the thermodynamic data, combustion reaction, and molar mass.
