mE + nf ⇋ pG + qH In the equation above, the equilibrium constant is given by
Equilibrium constant is = the product of the concentration of each of the products raised to the power of their coefficients divided by the concentration of each of the reactants raised to the power of their coefficients.
Now for the right answer to the above question:
- Option A is incorrect. it should be products parameters / reactants parameters and not the inverse.
- Option B is also incorrect.
- C is correct. products parameters / reactants parameters, correct.
- D is not the correct answer. Concentration of each of the reactants and products must be powered by their corresponding coefficients.
You may please note these/this:
- Always remember to power the concentration of the products and reactants by their coefficients.
- And also the product parameters should be the numerator, while the reactants parameters should be under.
