We can get Kp value from this formula:
Kp = Kc(RT)^Δn
when Kc= 0.135
and R = 0.08206 L.atm/mol.K
and Δn = total number of moles of products - total number of moles of reactants
= 1+3-2 = 2
T= tempreature in kelvin = 1615 °C+273 =1888 K
so by substitution:
∴ Kp = 0.135 * (0.08206 * 1888)^2
= 3240.4
Formation of hydrates is considered to be a chemical change.
Let's assume that the gas has ideal gas behavior.
Then we can use ideal gas equation,
PV = nRT
Where, P is Pressure of the gas (Pa), V is volume of the gas (m³), n is the number of moles of gas (mol), R is the Universal gas constant (8.314 J mol⁻¹ K⁻¹) and T is the temperature in Kelvin (K)
The given data for the gas is,
P = 2.8 atm = 283710 Pa
V = 98 L = 98 x 10⁻³ m³
T = 292 K
R = 8.314 J mol⁻¹ K⁻¹
n = ?
By applying the formula,
283710 Pa x 98 x 10⁻³ m³ = n x 8.314 J mol⁻¹ K⁻¹ x 292 K
n = 11.45 mol
Hence,moles of gas is 11.45 mol.
Answer:
35
