Calculate average molar heat capacity at...

Calculate average molar heat capacity at constant volume of gaseous mixture contained 2 mole of each of two ideal gases `(C _(v,m) = (3)/(2) R ) and B ( C _(v,m) = (5)/(2) R),`

A

R

B

2R

C

3R

D

8R

Text Solution

Verified by Experts

The correct Answer is:
B
Average `C _(v,m) = ( n _(1) C _(v,m) + n _(2) C _(v.m _(2)))/( n _(1) + n _(2)) = ( 2 xx (3)/(2) R+2 xx (5)/(2) R)/(2 + 2) = 2R `
