MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

The balanced chemical equation for the thermal decomposition of potassium chlorate is: 2KClO_3 2KCl + 3O_2 At STP, 22.4\ lit of oxygen gas corresponds to 1\ mole of O_2. From the stoichiometry of the reaction, 3\ moles of O_2 are produced by heating 2\ moles of KClO_3. Therefore, the number of moles of KClO_3 required to produce 1\ mole of O_2 is 2 3 \ mole . Answer: 2 3 \ mole
