NiO is to be reduced to nickel metal in an industrial process by use of the reaction:NiO(s) + CO(g) <-----> Ni(s) + CO2(g)
slavikrds [6]

Answer:

The reaction will occur, in the forward direction, and NiO will be reduced to Ni

Explanation:

Step 1: Data given

Kp = 6.0 * 10²

Pressure of CO = 150 torr

Total pressure never exceeds 760 torr

Step 2: The balanced equation:

NiO(s) + CO(g) ⇆ Ni(s) + CO2(g)

Step 3: Calculate P(CO) and P(CO2)

For this equilibrium, the expression for Kp is:

Kp = P(CO2)/P(CO) = 6.0*10^2

(NiO and Ni are solids so do not change anything to the Kp

⇒ with P(CO) = 150 torr

⇒ P(CO) = 760 - 150 = 610 torr

Step 4: Calculate the reaction quotient

Q = 610/150 = 4.1

Q<<< Kp

There are more reactants than products. As a result, some of the reactants will become products, causing the reaction to shift to the right.

This means the reaction will proceed in the forward direction, and NiO will be reduced to Ni.

The palmetto landfill in greer, sc supplies over 50% of the energy for the bmw plant there. this reduces carbon dioxide emission
Verdich [7]
Hello there!

The answer is 92000 tons per year

The palmetto landfill supplies methane (CH₄) for the BMW plant there. The gas is used to operate the turbines used to power the BMW campus. It reduces carbon dioxide emissions because the combustion of methane produces fewer CO₂ than the combustion of other gases like propane or butane, which are commonly used for powering turbines.
