JEE Main 2014 Chemistry question
The molar heat capacity of is 10 cals at 1000 K. The change in entropy associated with cooling of 32 g of vapour from 1000 K to 100 K at constant pressure will be: (D = deuterium, atomic mass = 2u)
Answer: (2)
Solution
The molar mass of is g/mol, so 32 g is exactly one mole. Then nC_p$ =
