Question

the synthesis of water proceeds according to this equation:
2h₂(g) + o₂(g) → 2h₂o(g)
how can the rate of this reaction be increased?
by increasing the temperature of the reactants
by increasing the temperature of the products
by decreasing the temperature of the reactants
by decreasing the temperature of the products
done

Explanation:

To determine how to increase the reaction rate for \(2\text{H}_2(\text{g}) + \text{O}_2(\text{g})
ightarrow 2\text{H}_2\text{O}(\text{g})\), we use the principle that reaction rate is affected by the energy of reactant particles. Increasing the temperature of reactants increases their kinetic energy, leading to more frequent and energetic collisions, which speeds up the reaction. Increasing product temperature or decreasing reactant/product temperature does not increase the rate (decreasing temperature slows reactions, and product temperature doesn't directly affect reactant collisions). So the correct option is the one about increasing reactant temperature.

Answer:

A. by increasing the temperature of the reactants
