Which of the following is the correct expression for the rate of the following reaction? Note: not all species are gaseous.

CuO(s) + H2S (g) <--> Cu(s) + H2O (g)

A.
[Cu] x [H2O] / ([CuO] x [H2S])

B.
[H2O] / [H2S]

C.
[CuO] x [H2S] / ([Cu] x [H2O])

D. None of these are correct

would it be C?

Yes

Absolutely no.

what would

it be

what was the answer?

To determine the correct expression for the rate of the given reaction, we need to consider the stoichiometric coefficients of the reactants and products in the balanced chemical equation. The rate expression can be determined by looking at the change in concentration of each species with respect to time.

In this case, the balanced equation is:

CuO(s) + H2S(g) <--> Cu(s) + H2O(g)

From the balanced equation, we can determine the stoichiometric coefficients:

- The coefficient of CuO is 1.
- The coefficient of H2S is 1.
- The coefficient of Cu is 1.
- The coefficient of H2O is 1.

The correct expression for the rate of this reaction can be written using the general rate law form:

Rate = k[A]x[B]y

Where [A] and [B] represent the concentrations of reactants, and x and y are the orders of the reaction with respect to each reactant. However, we need experimental data or additional information to determine the values of x and y.

The given options are:

A. [Cu] x [H2O] / ([CuO] x [H2S])
B. [H2O] / [H2S]
C. [CuO] x [H2S] / ([Cu] x [H2O])
D. None of these are correct

Since we don't have information about the specific rate constants or reaction orders, we cannot determine the correct rate expression. Thus, the correct answer is D. None of these are correct.
