question 125

Multiple Choice

• B)K is unitless because the units of the concentrations or partial pressures in the expression are dropped for convenience.
• C)K is unitless because the units of the concentrations or partial pressures in the expression cancel if the equilibrium expression is written correctly.
• D)K has units that reflect the units of the concentrations or partial pressures in the K expression.
• E)K has units of M or atm depending on whether solutions or gases are involved.
