Q 62 For gas 'A' in a calorimeter heat evolved is 250 kJ/mol For 0
2 mol of A, temperature rise from 298 K to 300K Find out heat
capacity of calorimeter -
(1) 12 5 kJ/K
(2) 25 kJ/K
(3) 50 kJ/K
(4) 100 kJ/K

Raveena Sharma · Accepted Answer

The solution is as follows:

For 0 2 mole, the energy released is 250 kJ/mol
For 1 mole energy released is 2500 2=50 kJ/mol

q = n Cp∆TCp = qn×∆T     =501×2=25 kJ/K

Correct option is (2)
