Enthalpy Flashcards
1
Q
activation energy
A
minimum energy required for a reaction to take place
2
Q
standard conditions
A
298K
100 kPa
1 mole
3
Q
enthalpy change
A
change in enthalpy when one mole of the reaction takes place
4
Q
specific heat equation
A
q = mcΔT
q = heat
m = mass of water
c = SH of water
ΔT = change in water temp
5
Q
ΔHc
A
ΔH = q/n
ΔH = KJ mol
6
Q
Hess’ law
A
the enthalpy change of a reaction is independent to the route taken
7
