Why does the reaction of Mg(s) with O2(g) to form MgO(s) begin when a piece of Mg(s) ribbon is held in a Bunsen burner flame?
gpt
The reaction begins because the reactants are activated by heat from the Bunsen burner flame.
Explanation: The heat transfers energy to overcome the activation energy barrier and initiate the exothermic reaction. This results in a faster movement and increased collision rates between reactant particles, making it more likely for them to react successfully.
