Volume of a sphere = 4/3 x pi x r^3
When put a fraction of volume constant 4/3 x pi cancels out.
So only cube of radii remains.
Radius of proton = 10^-15 m (Fact; remember it)
Radius of total Hydrogen atom = 0.529 × 10^−10 m
Fraction of Volumes : R'^3/R^3 = (R/R)^3
Fraction = ((10^-15)/(0.529 × 10^−10m.))^3= (1/52900)^3 =
6.755 x 10^-15
Effective collisions are those that result in a chemical reaction. In order to produce an effective collision, reactant particles must possess some minimum amount of energy. This energy, used to initiate the reaction, is called the activation energy.
