When two mole of an ideal gas (C(p,m)=(5...

When two mole of an ideal gas `(C_(p,m)=(5)/(2)R)` heated from 300 K to 600 K at constant pressure, the change in entropy of gas `(DeltaS)` is :

A

`(3)/(2)" R " " In " 2`

B

`-(3)/(2)" R In " 2`

C

`5 "R In" 2`

D

`(5)/(2) "R In" 2`

Text Solution

Verified by Experts

The correct Answer is:
C
`DeltaS = nC_(p.m) "In" (T_(2))/(T_(1)) = 2 xx (5)/(2)"R In" (600)/(300) = 5"R In 2`
