Rate Of Reaction Flashcards
1
Q
What does Arrhenius equation tell us
A
It shows that increasing the temperature will increase the rate constant k
2
Q
Give Arrhenius equations
A
K=Ae(-Ea/RT)
K=rate constant
Ea=activation energy
R=gas constant
T=Temperature lnk
3
Q
In arrenhieus equation what is plotted on the X and Y-axis respectively
A
Y-axis-Ln K (time
X-axis-1/temperature
4
Q
State the 2 types of graph when talking about the rate equation
A
Concentration-rate
Concentration-time
5
Q
How do u go about working out the order of reaction on a concentration-time graph
A
By using half life so working out the rate each time the concentration has halved
6
Q
State how you would work mole fraction
A
Number of moles of gas
Over total number of moles of all gases
7
Q
How is partial pressure worked out
A
Mole fraction * total pressure
