Well, percent ionization, simply allows you to find X which is the change in amount of substance into the final amount, it is dependent on the initial concentration of the substance present that is being dissociated.

For example, if the percent dissociation of CH3COOH is 1.5 % for an initial concentration of 0.15, then to solve for x, you would need to write percent as a decimal and solve.

% dissociation = X/Concentration of substance dissociated

0.015 = X/0.15

X = 0.0025.

Now since you know X, use the ice tables to solve for concentrations of species at equilibrium and plug in Kc expression.

The volume of a sample of gas at 0 degrees Celsius is 100 liters. If the volume of the gas is increased to 200 liters at constan

Anastasy [175]

Answer:

The answer to your question is: T = 546°K

Explanation:

V1 = 100 l

T1 = 0°C = 273°K

V2 = 200 l

T2 = ?

Pressure = constant

Formula

Charles law relates volume vs temperature

$\frac{V1}{T1} = \frac{V2}{T2}$

$T2 = \frac{V2T1}{V1}$

Substitution

$T2 = \frac{(200)(273)}{100}$

$T2 = \frac{54600}{100}$

Result

T2 = 546°K
