Explanation:
Hello,
Based on the statement of the equilibrium law:
By increasing (doubling) the amount of carbon monoxide, the production of nickel will increase since its amount is directly proportional with its pressure, so, by adding more reactant (in this case carbon monoxide), the equilibrium is rightward shifted based on Le Châtelier's principle even when solid either reactants or products are not contemplated in the equilibrium law.
Best regards.
Answer:
125.84 g/mol is the molar mass of the unknown gas.
Explanation:
Let the volume of the gases effusing out be V.
Effusion rate of the unknown gas =
Effusion rate of the nitrogen gas =
Molar mass of unknown gas = m
Mass of nitrogen gas = 28 g/mol
Graham's law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:
125.84 g/mol is the molar mass of the unknown gas.
