Answer : The concentration of ion, pH and pOH of solution is,
, 1.05 and 12.95 respectively.
Explanation : Given,
Concentration of ion = 0.090 M
pH : It is defined as the negative logarithm of hydrogen ion or hydronium ion concentration.
The expression used for pH is:
First we have to calculate the pH.
The pH of the solution is, 1.05
Now we have to calculate the pOH.
The pOH of the solution is, 12.95
Now we have to calculate the concentration.
The concentration is,
<u>Answer:</u>
<u>For 1:</u> The value of for the chemical equation is -24.636 kJ/mol
<u>For 2:</u> The value of for the chemical equation is -20.925 kJ/mol
<u>Explanation:</u>
For the given chemical equation:
To calculate the for given value of equilibrium constant, we use the relation:
.....(1)
where,
= ? kJ/mol
R = Gas constant =
T = temperature = 2000 K
= equilibrium constant in terms of partial pressure = 4.40
Putting values in above equation, we get:
Converting this into kilo joules, we use the conversion factor:
1 kJ = 1000 J
So, -24636.12 J/mol = -24.636 kJ/mol
Hence, the value of for the chemical equation is -24.636 kJ/mol
The expression of for the given chemical equation is:
We are given:
Putting values in above equation, we get:
Now, calculating the value of by using equation 1:
R = Gas constant =
T = temperature = 2000 K
= equilibrium constant in terms of partial pressure = 3.52
Putting values in equation 1, we get:
Converting this into kilo joules, we use the conversion factor:
1 kJ = 1000 J
So, -20925.68 J/mol = -20.925 kJ/mol
Hence, the value of for the chemical equation is -20.925 kJ/mol
