Chemical Equilibrium Flashcards
1
Q
Phase
A
Mechanically separable parts of a system
2
Q
Mixture of solids is always
A
HETEROGENEOUS
3
Q
Mixture of liquid is either
A
HETEROGENEOUS or HOMOGENEOUS
4
Q
MIxture of gases is always
A
HOMOGENEOUS
5
Q
Active Mass
A
Acitivity Coefficient(Usually 1) * Molar Concentration
Assumption: 100% conversion of reactant into product
6
Q
Acitivity Coefficient
A
Fraction of Molecules which will cross the energy barrier to become product
7
Q
Three types of k equilibrium
A
- Kc - Concentration of product and reactant
- Kp - Partial Pressure of product and reactant
- Kpc - Conc. and Partial Pressure
8
Q
Relation between kp and kc
A
Kp = Kc(RT)^delta ng, where delta ng = Sum of coefficient of gaseous products - gaseous reactant
9
Q
Effect of addition of inert gas
A
There will be no change in k-equilibrium no matter how many moles of inert gases are added
