A) +20.1 kJ
B) - 20.1 kJ
C) -20.1 kJ
D) +20.1 kJ
Correct Answer: A
Solution :
Work done in isothermal compression can be calculated as follows \[W=-nRT\,\,In\,\,\frac{{{V}_{2}}}{{{V}_{1}}}\] \[=\,\,-5\times 8.314\times 300\times 2.303 log \frac{40}{200}\] \[=\,\,\,-1500 \times \,\,8.314\,\,\times \,\,2.303\,\,\times \,\, \left( -\,log 5 \right)\] \[=\,\,\,+ 20.1 kJ\]You need to login to perform this action.
