REACTION RATE

COLLISION THEORY

HEAT ENERGY IS ABSORBED TO BREAK BONDS

In order for a reaction to occur, the particles in the chemical reaction must collide.

If a stress is applied to a system at equilibrium, the system shifts in the direction that relives the stress.

HEAT ENERGY IS RELEASED TO FORM BONDS.

THIS SUBSTANCE SLOWS DOWN THE RATE OF A CHEMICAL REACTION. IT CAN ALSO COMPLETELY STOP A CHEMICAL REACTION FROM OCCURRING.

THE SPEED AT WHICH A CHEMICAL REACTION OCCURS

THE AMOUNT OF ENERGY REQUIRED FOR A CHEMICAL REACTION TO OCCUR.

A BALANCED CHEMICAL EQUATION THAT INCLUDES ENTHALPY CHANGE. USUALLY EXPRESSED IN ∆H (HEAT)

PV=nRT

INCREASES THE RATE OF A CHEMICAL REACTION BY LOWERING THE ACTIVATION ENERGY
