Ch 14 & 15(gas And Acid Quilibrium

Question 1

Reversing a reaction

Multiply or dividing reaction

Adding reactions

Answer 1

1/k

(K)^n or (k)^1/n

Krxn1 X Krxn2

Question 2

Partial pressure

Answer 2

Pi = (M)RT

Kp= Pb/ Pa

Kp= Kc(RT)^delta n

Delta n = (coefficients of products coefficients of reactants)

Question 3

Q rxn quotient

Answer 3

Products/ reactants

But use initial concentrations or pressures

Question 4

Q>K

Q

Answer 4

Excess products

Lack of products

Equilibrium

Question 5

Increase volume

Answer 5

Equi shifts to side with greater mols of gas

Question 6

Decrease volume

Answer 6

Equi shifts to lesser side of mols of gas

Question 7

Increase temperature

Answer 7

Equi shift away from heat side

Question 8

Decrease temp

Answer 8

Equi shifts toward heat side
