For the same raise in temperature of two moles of gas at constant pressure, the heat required for triatomic gas is K times the heat required for  monoatomic gas. The value of K is

molar specific heat of gas at constant pressure for tri atomic gas (6° of freedom)Cp=4R molar specific heat of gas at constant pressure is Cp Cp=52R for monoatomic gasheat required for raise in temperature of gas at constant pressure is Q=nCp∆TQtriatomic=kQmonotomic substitute the valuesn(4R)∆T=kn(5R2)∆T ∴K=4R52R=85Heat required is 85  times.
