<span>In terms of energy and entropy, systems in nature tend to undergo changes toward lower energy and higher entropy. Entropy is important as it describes the flow and distribution of energy. For a process to to occur spontaneously, it is a necessary condition that the entropy of the system undergoing the process to increase. If the entropy decreases, then that process cannot occur spontaneously. It needs some work/ energy to be pumped in in order for the process to occur</span>
Answer:
MgSo4 is the right answer
The rate of reaction increases
Answer:
5.72 moles of nitrogen oxide are formed when 2.86 moles of nitrogen react.
Explanation:
Given data:
Moles of NO formed = ?
Moles of N₂ reacts = 2.86 mol
Solution:
Chemical equation:
N₂ + O₂ → 2NO
Now we will compare the moles of nitrogen with nitrogen oxide from balance chemical equation.
N₂ : NO
1 : 2
2.86 : 2/1×2.86 = 5.72 mol
So 5.72 moles of nitrogen oxide are formed when 2.86 moles of nitrogen react.
Answer:The number of moles will remain the same in the two cases
so we can equate using ideal gas equation which is PV =nRT
V2 = 3100 L
