Question

For gas A in a calorimeter heat evolved is 250 kJ/mol. For 0.2 mol of A, temperature rise from 298 K and 300 K. Find out heat capacity of calorimeter

• A. $12.5$ kJ/K
• B. $25$ kJ/K
• C. $50$ kJ/K
• D. $100$ kJ/K

Answer 1

The correct option is A $12.5$ kJ/K

We know that, $Q=nC△T$

Where, $Q=\text{heat evolved}n=\text{number of moles}C=\text{heat capacity}$

$\therefore$ $250=0.2\times C\times (398-298)C=\frac{250}{0.2\times 100}C=12.5KJ/K$
