Statement 1: For the same mole of SO2 and O2 gases, more heat is needed for SO2 gas than O2 gas for the same increase in the temperature of the gas.
Statement 2: SO2 gas, being triatomic, has higher heat capacity than the diatomic O2 gas.
Options:
Answer:
A
Solution:
The nonlinear triatomic SO2 has more vibrational and rotational modes than diatomic O2, so its molar heat capacity (at constant V or P) is larger. q=nCΔ T is therefore larger for SO2. Both correct, II is the reason. Answer (a).
