A system consisting of one mole of an ideal diatomic gas absorbs 200J of heat and does 50J of work on surroundings. What is the change in temperature if vibrational modes of motion are inactive?

A

`(150J mol^(-1))/(8.314 xx (5)/(2))`

B

`(150J mol^(-1))/(8.314 xx (3)/(2))`

C

`(150J mol^(-1))/(8.314 xx (7)/(2))`

D

`(150J mol^(-1))/(8.314 xx (4)/(3))`

Text Solution

Verified by Experts

The correct Answer is:
A
`Delta E = (3)/(2) R Delta T + R Delta T` (Rot + Trans)
