Answer:
0.0097 mol·L⁻¹
Explanation:
The balanced equation is
2NOCl ⇌ 2NO₂ + Cl₂
Data:
Your value of Kc is incorrect. It should be
Kc =1.6 × 10⁻⁵
[NOCl] = 0.50 mol·L⁻¹
[NO] = 0.00 mol·L⁻¹
[Cl₂] = 0.00 mol·L⁻¹
Calculations:
1. Set up an ICE table.
2. Calculate the equilibrium concentrations
This is a cubic equation. Some calculators can solve cubic equations, but we can solve it by the method of successive approximations.
We will make changes to the right-hand side until the calculated value of x no longer changes,
(a) 1st approximation
Assume that 2x is negligible compared to 0.50. Then
(b) 2nd approximation
Assume that x= 0.010. Then
(b) 3rd approximation
Assume that x= 0.0097. Then
No change, so x = 0.0097.
[Cl₂] = x mol·L⁻¹ = 0.0097 mol·L⁻¹
Check:
It checks.
Answer:
Explanation:
According to the Dalton's law of partial pressure, the total pressure of the gaseous mixture is equal to the sum of the pressure of the individual gases.
Partial pressure of carbon dioxide = 401 mmHg
Partial pressure of hydrogen gas = 224 mmHg
Total pressure,P = sum of the partial pressure of the gases = 401 + 224 mmHg = 625 mmHg
Also, the partial pressure of the gas is equal to the product of the mole fraction and total pressure.
So,
Similarly,
Velocity is defined as displacement over time. Could you have possible meant viscosity? If so, viscosity is defined as the state of being thick, sticky, and semifluid in consistency, due to internal friction. And example of a substance with a high viscosity would be honey.
