Question

Reactivity of metal increases with increase in temperature because:

• A. It increases intermolecular attraction between molecules.
• B. It increases collision between molecules.
• C. It decreases pressure.
• D. It increases pressure and hence decreases intermolecular spaces.

Answer 1

The correct option is B

It increases collision between molecules.

Reactivity of metal increases with increase in temperature because temperature directly increases the Kinetic Energy of the Electrons. These electron with increased Kinetic Energy vibrate with greater energy and cause more collisions. Hence the Metal's reactivity increases.
