◻ Decreasing the temperature decreases the kinetic energy of the mastant. Wid the reaction poes more slowly.
◻ If the heat of reaction,
A.H, is megative, the energy of fle polless in higher than the energy of the reactunts and the reaction is exothermic.

◻ Rnactants mast collide with proper eriestation and with every grater than er equal to the activation energy for a maction to occur.
◻ Increasing the concentration of reactuns increases the meler of collinicits, and fle reaction goes fauter.
