A chemical reaction occurs when reactant particles 2 points are separated by great distances have no attractive forces between them collide with proper energy and proper orientation convert chemical energy into nuclear energy. True / False.

True

Explanation:

According to the collision theory which seeks to explain how and why reactions occur. There must be a collision between the particles, molecules, atoms etc.

However not all collisions leads to reactions. A minimum amount of energy referresdd to as  the activation energy must be achieved. Also the molecules need to be of proper/right orientation.

This is present in the mathematical equation;

k =Ae^(-Ea/RT)

Where Ea = activation energy

A = A is the pre-exponential factor, a constant for each chemical reaction. According to collision theory, A is the frequency of collisions in the correct orientation
