Rates Of Reaction Flashcards
1
Q
Heat of Reaction
A
(Delta H) is the net change of chemical potential energy of the system
2
Q
Exothermic Reaction
A
Are reactions which transform chemical potential energy into thermal energy
3
Q
Endothermic reactions
A
Are reactions which transform thermal energy into chemical potential energy
4
Q
Activation Energy
A
Is the minimum energy required to start chemical reaction or the energy required to form the activated complex
5
Q
Activated complex
A
As high energy, unstable transition state between the reactions and the products
6
Q
Reaction rate
A
Is the change in amount or concentration per unit time of either a reactant or product
7
Q
A catalyst
A
Is a substance that increases the rate of the reaction but remains unchanged at the end of the reaction
