An insulating cylinder contains 4 moles of an ideal diatomic gas. When a heat 
is supplied, to it, 2 moles of the gas molecules dissociate. If the temperature of the gas remains constant, then the value of 
is ( 
- universal gas constant)

Text Solution
Verified by ExpertsThe correct answer is:
B
Heat supplied " 
" is given by:
Initially cylinder contains 4 moles of diatomic gas,
2 moles of diatomic gas dissociate into monoatomic gas.
Hence there are 4 moles of monoatomic gas and 2 moles of diatomic gas.
Final Internal Energy is given by:
Thus Heat supplied is,
