Collision Theory of Chemical Reactions

In a reversible reaction, the enthalpy change and the activation energy in the forward direction are respectively $-\mathrm{x} \mathrm{kJ} {\mathrm{mol}}^{-1}$ and $\mathrm{y} \mathrm{kJ} {\mathrm{mol}}^{-1}$. Therefore, the energy of activation in the backward direction is

1. Reactant molecules should have enough kinetic energy to overcome the threshold energy barrier.
2. Reactant molecules that collide, should have proper _____ based on three-dimensional space. 

Collision theory is applicable to 

The minimum energy that all colliding molecules must possess in order to make the collisions effective is called _____ energy.(threshold/activation)
