Coming Up With Reaction Quotient

In summary, the reaction quotient is a measure of relative concentrations of products and reactants in a chemical reaction at a specific point in time. It is calculated by dividing the concentration of products by the concentration of reactants, with each concentration raised to the power of their respective coefficients in the balanced chemical equation. The reaction quotient differs from the equilibrium constant in that it is calculated at a specific point in time, while the equilibrium constant is a constant value representing the concentrations at equilibrium. The reaction quotient can provide information about the state of a reaction, such as whether it is at equilibrium, which direction it is proceeding in, and how far it has progressed towards equilibrium. It can also be used in practical applications to predict reaction direction, determine optimal conditions,

Can't figure this one out. Here's the problem.

Solid molybdenum (VI) oxide reacts with gaseous xenon difluoride to form liquid molybdenum(VI) fluoride, xenon gas, and oxygen gas. Write the Qc for this reaction.

I know Qc is products over reactants and pure liquids and solids are not included.

So this is what I came up with. Its wrong though.

Qc= [XeF2]3 / [Xe]3 [O2]

Any help would be great. Thanks.

1. What is the balanced reaction equation?

2. If it is products over reactants, why do you have XeF2 - a reactant - in the numerator?
 

1. What is a reaction quotient?

A reaction quotient is a measure of the relative concentrations of products and reactants in a chemical reaction at a specific point in time.

2. How is the reaction quotient calculated?

The reaction quotient is calculated by dividing the concentration of products by the concentration of reactants, with each concentration raised to the power of their respective coefficients in the balanced chemical equation.

3. How is the reaction quotient different from the equilibrium constant?

The reaction quotient is calculated at a specific point in time, while the equilibrium constant is a constant value that represents the relative concentrations of products and reactants at equilibrium.

4. What information can be obtained from the reaction quotient?

The reaction quotient can give information about whether a reaction is at equilibrium, which direction the reaction is proceeding in, and how far the reaction has progressed towards equilibrium.

5. How can the reaction quotient be used in practical applications?

The reaction quotient can be used to predict the direction of a reaction and to determine the optimal conditions for a desired reaction. It can also be used to monitor the progress of a reaction and to calculate the equilibrium constant.
