Find the heat absorbed from the surroundings when 15 g of O₂ reacts according to the equation O + O₂ $\rarr$ O₃, $\Delta$H°_rxn= -103 kJ/mol.

Question

Quizplus · Accepted Answer

The reaction involves the formation of ozone (O3) from oxygen (O2). The molar mass of O2 is 32 g/mol. Therefore, 15 g of O2 is 15/32 moles. The reaction releases 103 kJ per mole of O2. Thus, the heat absorbed is (15/32) * 103 kJ = 48 kJ.
