Determine the value of kc for the following reaction if the equilibrium concentrations are as follows: [hcl]eq = 0.13 m, [hi]eq = 5.6 × 10-16 m, [cl2]eq = 0.0019 m. 2 hi(g) + cl2(g) ⇌ 2 hcl(g) + i2(s)

The value of is

Explanation:

Concentration equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric coefficients. It is represented by

For a general chemical reaction:

The expression for is written as:

For the given chemical reaction:

The expression for is written as:

The concentration for solid substances are taken to be 1.

We are given:

Putting values in above equation, we get:

Hence, the value of is

explanation:

crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
