Answer:
Explanation:
<u>1) Balanced chemical equation:</u>
<u>2) Mole ratio:</u>
- 2 mol S : 3 mol O₂ : 2 mol SO₃
<u>3) Limiting reactant:</u>
n = 6.0 g / 32.0 g/mol = 0.1875 mol O₂
n = 7.0 g / 32.065 g/mol = 0.2183 mol S
Actual ratio: 0.1875 mol O₂ / 0.2183 mol S =0.859
Theoretical ratio: 3 mol O₂ / 2 mol S = 1.5
Since there is a smaller proportion of O₂ (0.859) than the theoretical ratio (1.5), O₂ will be used before all S be consumed, and O₂ is the limiting reactant.
<u>4) Calcuate theoretical yield (using the limiting reactant):</u>
- 0.1875 mol O₂ / x = 3 mol O₂ / 2 mol SO₃
- x = 0.1875 × 2 / 3 mol SO₃ = 0.125 mol SO₃
<u>5) Yield in grams:</u>
- mass = number of moles × molar mass = 0.125 mol × 80.06 g/mol = 10.0 g
<u>6) </u><em><u>Percent yield:</u></em>
- Percent yield, % = (actual yield / theoretical yield) × 100
- % = (7.9 g / 10.0 g) × 100 = 79%
Answer:- A) Exothermic, B) Reactant side(left side), C) Product side(right side), D) Reactant side(left side) and E) Le-chatelier's principle.
Explanations:- A) 
of the reaction is negative and it indicates an exothermic reaction.
B) Equilibrium shifts to the reactant side if nitrogen gas is removed. If anything is added then reaction moves in a direction where this added component is used and if something is removed then reaction moves in a direction where this removed component is formed.
C) Exothermic reactions are favored at low temperature and endothermic reactions are favored at high temperature. The temperature is lowered, so the reaction will shift to the product side.
D) The reaction shifts to the reactant side if ammonia is added so that it could be used to reestablish the equilibrium.
E) Le-chatelier's principle helps to answer B-D. As per this principle, reaction shifts in a direction where the stress is relieved. It means if anything is added then it must be used and if something is removed then it must be formed.

Answer:
The forward and the reverse processes are both spontaneous. (Ans. B)
Explanation:
When a system is at equilibrium state, then the rate of backwards, and forward, both reactions becomes equal. Which means the forward and the reverse processes are both spontaneous.
With the help of entropy change of the reaction, and Gibbs free energy we can determine the spontaneity of a reaction. If entropy changes is positive, and Gibbs free energy changes a negative, then the reaction will say to be spontaneous.
