Rate Of Reaction

What is the equation for rate of reaction?
Mean rate of reaction = around of reactant used / time taken
1 of 17
What are Rates of Reaction?
Pressure, Concentration, Catalyst, Temperature, Surface Area
2 of 17
What is a Reversible reaction?
Where the products of reaction can react to produce original reactants
3 of 17
What is Equilibrium?
Reversible reaction takes place in closed system then a state of equilibrium will always be reached
4 of 17
What happens when amount of reactants & products reach a balance?
Concentration stop changing
5 of 17
What happens when there is a closed system?
None of reactants or products can escape
