The ratio of specific heats of a gas is ...

The ratio of specific heats of a gas is 1.4. if the value of `C_(V)` is 20.8 J/mol K, then the `C_(P)` is

A

3.93 cal/mol K

B

4.93 cal/mol K

C

5.93 cal/mol K

D

6.93 cal/mol K

Text Solution

Verified by Experts

The correct Answer is:
D
`(C_(p))/(C_(V))=1.4`
`C_(p)=1.4C_(V)=1.4xx20.8`
`=29.12J//mol` K
`C_(p)=(29.12)/(4.2)=6.93` cal/mol K
