Question

The entropy change when two of ideal monoatomic gas is heated form `200 to 300^(@)C` reversiblity and isochorically?
A. `(3)/(2)R ln.((300)/(200))`
B. `(5)/(2)R ln.((573)/(273))`
C. `3R ln.((573)/(473))`
D. `(3)/(2)R ln.((573)/(473))`

Answer 1

Correct Answer - C
`DeltaS = nC_(V) In (T_(2))/(T_(1))`
`= 2 xx (3)/(2) R In (573)/(473)`
