Rate Determining Step
|
Slowest step
|
|
|
reaction rate is determined by
|
1. how frequently reactant molecules collide
2.orientation of colliding molecules 3.energy |
|
|
Exothermic Reaction
|
Energy of products is lower then energy of reactants, heat is released, H is negative
|
|
|
Endothermic reaction
|
Energy of products is higher then energy of reactants, heat is consumed, H is positive
|
|
|
Reaction rate rules
|
1. Lower Ea, faster reaction
2.Greater concentration of reactants, faster reaction 3. Higher temp., faster reaction |
|
|
rate law
|
aA + bB --> cC + dD
rate = k [A]^x [B]^y x - order of reaction with respect to A y- order of reaction with respect to B x+y = overall order of rxn |
|
|
Can rate law be derived
|
NO, only EXPERIMENTALLY
|
