Consider the following reaction, equilibrium concentrations, and equilibrium constant at
a particular temperature. Determine the equilibrium concentration of H2O(g): [C2H4]eq = 0.015
M, [C2H5OH]eq = 1.69 M
C2H4(g) + H2O(g) ? C2H5OH(g) Kc = 9.0

Equilibrium concentration of is 12.5 M

Explanation:

Given reaction:

Here,

where represents equilibrium constant in terms of concentration and species inside third bracket represent equilibrium concentrations

Here, , and

So,

Hence equilibrium concentration of is 12.5 M

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
