Question

What is diffused sunlight and its role in reaction?

Answer 1

Diffused Sunlight

• Diffused light is a soft, diffused light that lacks the brightness and intensity of direct light.
• It diffuses and spreads out in all directions.
• As a result, it appears to encircle objects.
• It is a softer light that doesn't cast harsh shadows.

Role of diffused light in reaction

• In the presence of scattered sunlight, hydrogen gas (${\mathrm{H}}_2$) reacts with chlorine $\left({\mathrm{Cl}}_2\right)$ to generate $\mathrm{HCl}$.
• Because the reaction is explosive in direct sunshine and minimal in the dark, diffused light is required.
