If the reaction below produces 5,230 kJ of energy,how many grams of KCl will be produced? (KCl = 74.6 g/mol) 2 K (s)+ Cl₂ (g)$\rightarrow$ 2 KCl (g)$\Delta$H_rxn = -873.0 kJ

Question

Quizplus · Accepted Answer

The reaction releases 873.0 kJ per 2 moles of KCl. To produce 5,230 kJ, the amount of KCl produced can be calculated by setting up a proportion based on the stoichiometry of the reaction and the molar mass of KCl. $5230 kJ * \frac{2 moles KCl}{873.0 kJ} * 74.6 g/mole = 894 g$.
