The heat capacity of a bomb calorimeter is 500 J/^oC. When 0.1 g of a methane was burnt in this calorimeter, the temperature rose by 2^oC. The value of $Δ E$ per mole will be

Options:

Answer:

Solution:

$Δ E = - \frac{M}{w} \times C \times Δ t$

$= - \frac{16}{0.1} \times 500 \times 2 = - 160 \times 1 0^{3} J = - 160 kJ$ (minus sign is used as heat is evolved.)
