Pavel [41]

The Equation of reaction

C + O2 === CO2

First Blank spot would be

---- 3.5moles of O2

2nd spot

Up.... 1mole of CO2

Down ---- 2moles of Oxygen atoms

3rd spot

Up... --- 22.4L of CO2(1mole of any gas at STP contains 22.4L)

Down---- 1mole of CO2

Final answer --- 3.5 x 1/2 x 22.4

=39.2L of CO2

Write the equilibrium constant expression Kc for the following reaction.2H20(g) ---------> O2(g) + 2H2(g) <---------Do not

Komok [63]

Answer:

$K_c\text{ = }\frac{[O_2][H_2]\placeholder{⬚}^2}{[H_2O]\placeholder{⬚}^2}$

Explanation:

Here, we want to write the equilibrium constant expression

To write this, we raise the concentrations of the reactants and products to the coefficient before them. These concentrations are represented by square brackets in which the chemical formula of the compound is placed

We place the representation of the products over that of the reactants

We have the expression written as follows:

$K_c\text{ = }\frac{[H_2]\placeholder{⬚}^2[O_2]}{[H_2O]\placeholder{⬚}^2}$
