Given
Reaction
2SO₂+O₂⇔2SO₃+energy
Required
Changes to the formation of products
Solution
The formation of SO₃ is an exothermic reaction (releases heat)
If the system temperature is raised, then the equilibrium reaction will reduce the temperature by shifting the reaction in the direction that requires heat (endotherms). Conversely, if the temperature is lowered, then the equilibrium shifts to a reaction that releases heat (exothermic)
While on the change in pressure, then the addition of pressure, the reaction will shift towards a smaller reaction coefficient
in the above reaction: the number of coefficients on the left is 3 (2 + 1) while the right is 2
As the temperature decreases, the equilibrium will shift towards the exothermic reaction, so the reaction shifts to the right towards SO₃( products-favored)
And increasing the pressure, then the reaction shifts to the right SO₃( products-favored)⇒the number of coefficients is greater

Industry uses only about 18% while the others use around 70-90% of water.
Answer:
Percent error = 41%
Explanation:
Percent error:
Percent error is the difference between the measured value and actual value divided by actual value multiply by 100.
Given data:
Actual length of rope = 3.15 m
Measured length of rope = 1.85 m
Percent error = ?
Solution:
Formula:
Percent error = [measured value - actual value / actual value ] × 100
Now we will put the values in formula.
Percent error = [1.85 - 3.15 / 3.15 ] × 100
Percent error = [-1.3 /3.15 ] × 100
Percent error = -0.41 × 100
Percent error = 41%
The negative sign shows that measured value is less than the actual value but often results are reported in absolute value.
