Kinetics & Equilibria Flashcards
1
Q
Rate equation?
A
Rate = k[A][B][X]
2
Q
What is first order?
A
Rate is proportional to the change in concentration
3
Q
What is second order?
A
Rate is proportional to the concentration squared
4
Q
What is zero order?
A
Rate is unaffected by a change in concentration
5
Q
What does k represent?
A
Rate constant, varies with temperature
6
Q
What is the equation for k?
A
k = Ae⁻ᴱᵃ/ᴿᵀ
7
Q
What do A, Ea, R and T stand for?
A
A- constant
Ea- activation energy
R- gas constant
T- temperature (K)
8
Q
How do you find rate from a graph?
A
Find the equation of the tangent
9
Q
What is the equilibrium constant used for gas reactions?
A
Kp
10
Q
How is Kp calculated?
A
Using partial pressures
11
Q
How do you find mole fractions?
A
Moles of substance over total moles
12
Q
How do you find partial pressures?
A
Mole fraction x pressure
