1.

For aA + bB ⇌ cC + dD, Kc is

[C]^c[D]^d/([A]^a[B]^b)
[A]^a[B]^b/([C]^c[D]^d)
[C][D]/[A][B] always
c·d/(a·b)
2.

Pure solids and liquids are

always included
squared
omitted from the equilibrium expression
set to zero
3.

A very large K means

reactants are favoured
the reaction is fast
products are strongly favoured at equilibrium
no reaction
4.

If a reaction is reversed, the new K is

1/K
K
−K
K²
5.

If the coefficients of an equation are doubled, the new K is

K²
2K
K/2
√K
6.

When two reactions are added, the overall K is

the sum K₁ + K₂
the product K₁ × K₂
the difference
the ratio
7.

For H₂ + I₂ ⇌ 2HI at equilibrium, [H₂] = [I₂] = 0.10 M and [HI] = 0.70 M. Kc is

49
7.0
0.020
70
8.

Kp uses

molar concentrations
masses
moles
partial pressures of gases
9.

The value of K changes only with

concentration
pressure
a catalyst
temperature
