Calculation of Adsorption Coefficient
Slope of the plot = 2 x 10^-5 torr m^-3
Intercept of the plot = Vm = 4 x 10^-8 m^3
The equation for adsorption isotherm is given by:
1/V = K x P + 1/Vm
where,
V = volume of gas adsorbed
K = adsorption coefficient
P = pressure of gas
From the given data, we can write:
1/V = 2 x 10^-5 x P + 1/4 x 10^-8
On rearranging the above equation, we get:
V = (4 x 10^-8) / (1 + 2 x 10^-5 x P)
Now, we can plot the graph of V vs P and obtain a straight line with a slope of K and an intercept of Vm.
Therefore, the adsorption coefficient can be calculated as:
K = slope of the plot = 2 x 10^-5 torr^-1 m^3
K = 2 x 10^-5 x 10^12 (since 1 torr^-1 = 10^12 Pa^-1)
K = 2 x 10^7 Pa^-1
K = 2 x 10^7 / 101325 (since 1 atm = 101325 Pa)
K = 1.975 x 10^-4 atm^-1
K = 1.23 x 10^12 torr^-1 (rounded off to two decimal places)
Therefore, the adsorption coefficient is 1.23 x 10^12 torr^-1 (rounded off to two decimal places).
Slope of the plot = 2 x 10^-5 torr m^-3
Intercept of the plot = Vm = 4 x 10^-8 m^3
The equation for adsorption isotherm is given by:
1/V = K x P + 1/Vm
where,
V = volume of gas adsorbed
K = adsorption coefficient
P = pressure of gas
From the given data, we can write:
1/V = 2 x 10^-5 x P + 1/4 x 10^-8
On rearranging the above equation, we get:
V = (4 x 10^-8) / (1 + 2 x 10^-5 x P)
Now, we can plot the graph of V vs P and obtain a straight line with a slope of K and an intercept of Vm.
Therefore, the adsorption coefficient can be calculated as:
K = slope of the plot = 2 x 10^-5 torr^-1 m^3
K = 2 x 10^-5 x 10^12 (since 1 torr^-1 = 10^12 Pa^-1)
K = 2 x 10^7 Pa^-1
K = 2 x 10^7 / 101325 (since 1 atm = 101325 Pa)
K = 1.975 x 10^-4 atm^-1
K = 1.23 x 10^12 torr^-1 (rounded off to two decimal places)
Therefore, the adsorption coefficient is 1.23 x 10^12 torr^-1 (rounded off to two decimal places).
