The first molecule is a sensible molecule having complete octet of each atom such as C, H and O whereas the second molecule having hydrogen present between the aldehyde and methyl group and thus showing hydrogen is making bond with aldehyde and methyl as well which is not possible because hydrogen only having one electron in its octet due to which it can only form a single bond by sharing its valence electron.
<u>Answer:</u> The for the reaction is 54.425 kJ/mol
<u>Explanation:</u>
For the given balanced chemical equation:
We are given:
To calculate for the reaction, we use the equation:
For the given equation:
Putting values in above equation, we get:
Conversion factor used = 1 kJ = 1000 J
The expression of for the given reaction:
We are given:
Putting values in above equation, we get:
To calculate the gibbs free energy of the reaction, we use the equation:
where,
= Gibbs' free energy of the reaction = ?
= Standard gibbs' free energy change of the reaction = 46900 J
R = Gas constant =
T = Temperature =
= equilibrium constant in terms of partial pressure = 20.85
Putting values in above equation, we get:
Hence, the for the reaction is 54.425 kJ/mol
When y equals 5, x is 104.3
When y equals 3 then x is 108.3
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>
Substitute y = 5 in given expression
5 = 57.15 - 0.5(x)
5 = 57.15 - 0.5x
0.5x = 57.15 - 5
0.5x = 52.15
Divide both sides by 0.5
x = 104.3
Thus when y equals 5, x is 104.3
<h3><u>If y = 3 what is x ?</u></h3>Substitute y = 3 in given expression
3 = 57.15 - 0.5(x)
3 = 57.15 - 0.5x
0.5x = 57.15 - 3
0.5x = 54.15
Divide both sides by 0.5
x = 108.3
Thus when y equals 3 then x is 108.3
