chemical energetics Flashcards
1
Q
what is exothermic reaction
A
the transferal of thermal energy to the surroundings leading to an increase in the temperature of the surroundings
2
Q
what is endothermic reaction
A
takes in the thermal energy from the surroundings leading to a decrease in the temperature of the surroundings
3
Q
interpret reaction pathway of endothermic and exothermic reaction through a diagram
A

4
Q
what is the reaction of thermal energy called and reaction of endothermic and exothermic reaction
A
the transfer of thermal energy is called enthalpy change ∆H, ∆H is negative for exothermic reaction and positive for endothermic reactions.
5
Q
what is activation energy
A
activation energy E is the minimum energy that colliding particles must have to react
