Answer:
- 122.58 kJ
Solution:
According to following equation,
<span>2 Al + 3 Cl</span>₂ <span>→ 2 AlCl</span>₃ <span> δH</span>°<span> = -1408.4 kJ
</span>
When,
54 g (2 mole) Al on reaction releases = <span>1408.4 kJ heat
So,
4.70 g of Al will release = X kJ of Heat
Solving for X,
X = (4.70 g </span>× 1408.4 kJ) ÷ 54 g
X = - 122.58 kJ
