When the reaction mixture is heated, the average kinetic energy of the reactant particles increases. This means more particles have higher energies and so are able to reach or exceed the activation energy of the reaction. The activation energy is the minimum energy required for reactant particles...

- When a solid is heated, energy is supplied to the molecules. This energy increases the kinetic energy of the molecules, causing them to vibrate more vigorously. 5. Breaking of Intermolecular Forces: - As the kinetic energy increases, the vibrations become strong enough to overcome the strong...
Changes state: When a substance absorbs heat, its particles move apart due to the vibration of the particles. The increase in the intermolecular spaces causes a change in the state to occur. When ice cubes are heated, for example, they turn into water, which then turns into vapour when hea...
(i) When potassium chlorate isw heated in the presence of MnO(2), Oxygen gas is liberated. 2KCIO(3)overset(MnO(2))underset(Delta)to 2KCI+3O(2) (ii)
What happens when baking powder is heated?Baking powder produces carbon dioxide on heating, so it is used in cooking to make the batter spongy. How does heat affect baking powder? Baking soda, or sodium bicarbonate (NaHCO3), is a chemical that can undergo adecomposition reactionwhen heated. ...
