Question

Heat evolved in the complete combustion of 1.026 kg sucrose at constant pressure will be

C12H22O11(s) + 12O2(g) → 12CO2(g) + 11H2O(l); ΔH = −5.65 × 103 kJ

Options

A.1.695 × 104 kJ
B.5.65 × 103 kJ
C.1.883 × 103 kJ
D.3.22 × 104 kJ

Solution

$\frac{5.65 \times 10^{3}}{342} \times 1026 = 1.695 \times 10^{4}\text{ kJ}$
