<u>Answer:</u> The net chemical equation for the production of acrylic acid is given below.
<u>Explanation:</u>
We are given two intermediate equations:
<u>Equation 1:</u>
<u>Equation 2:</u>
To get the net chemical equation for the formation of acrylic acid from calcium carbide, carbon dioxide and water, we multiply the first equation by a factor of '6'.
The equation becomes:
<u>Equation 1:</u>
<u>Equation 2:</u>
Net chemical equation now becomes:
Hence, the net chemical equation for the production of acrylic acid is given above.
That point is called as EQUILIBRIUM, and then you have to note that value to compare with others
Boiling point stays the same, because it is not dependent on volume of the liquid. Boiling point is defined as temperature at which the liquid changes into vapour. It may depend on pressure, but it never depends on volume!
This answer to this question is a rule that is applied to any reaction taken at dynamic equilibrium, with respect to 500 K. In other words, you can say that this reaction is of no use to us -
In a chemical equilibrium, it is known that the forward and reverse reactions occur at equal rates. At this point the concentrations of products and reactants remain constant, or in other words do not change
