Question | Answer |
---|---|
Kinetics | how fast a reaction occurs; energy in movement |
Activation Energy | minimum energy to start a reaction |
catalyst | a reaction by lowering the activation energy |
Le Chatelerie's principle | if stress is applied to a system equillibrium then the system will respond in such a way to off et the stress applied |
equilibrium | when speed or rate of the forward reaction equals the speed or rate of the reverse reaction |
Kc | concentration of the products at equillibrium over concentration of reactants at equilibrium |
Kp | pressure of products at equilibrium over pressure of reactants at equilibrium |
rate | speed of a reaction |
homogenous catalyst | reactants and products are in the same phase |
heterogenous catalyst | reactants and products are in different phases |
half life | the amount of time that it takes for an isotope to decrease one half life its original concentration |
