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
South of the Antarctic Circle which is 66.5 degree south of the equator.
Explanation:
- December 21st and December 22 are very important dates for our planet because 21st December is one of the solstices, this is the day when the sun rays directly hit one of the two latitudes lines.
- In South of the Antarctic Circle and North of the Arctic Circle, there are 24 hours of daylight and darkness respectively. The sun rays directly fall along the tropic of Capricorn and passing through, Australia, South Africa and Brazil on 21st December.
Answer:
445.8 J of heat is absorbed by the water
Explanation:
Step 1: Data given
Mass of water = 32.0 grams
Initial temperature = 19.50 °C
Final temperature = 22.83 °C
Specific heat of water = 4.184 J.g°C
Step 2: Calculate the amount of heat absorbed by the water
Q = m*c*ΔT
⇒with Q = the heat absorbed = TO BE DETERMINED
⇒with m= the mass of water = 32.0 grams
⇒with c= the specific heat of water = 4.184 J/g°C
⇒with ΔT = the change of temperature = T2 - T1 = 22.83 °C - 19.50 °C = 3.33 °C
Q = 32.0 * 4.184 * 3.33
Q = 445.8 J
445.8 J of heat is absorbed by the water
