Chemical Equilib

Thermochemistry, Equilbrium, Reaction rates

TermDefinition
Chemical Equilibrium Concentration of product and reactants stops changing
This make reactions go faster Adding heat
This makes reactions go slower Decreasing concentration
Reversible reaction Reaction in which products can react to re-form reactants
Removing products in a reversible reaction Shifts the equilibrium to the right
Adding products in a reversible reaction Shifts the equilibrium to the left
To shift a reversible reaction to the right, you should: Add more reactant
To shift a reversible reaction to the left, you should: Add more product

What is a catalyst? Lowers the activation energy
What is a calorie? Amount of energy that increases temperature of 1 ml of water by 1 degree C
What is a joule? SI unit of energy; 1 cal = 4.182 joules
In an exothermic process, energy is a: product
In an endothermic reaction, energy is a: reactant
Will give off heat to the surroundings Exothermic reaction
Will absorb or take in heat from the surroundings Endothermic reaction
