Answer:
Average rate of reaction is 0.000565 M/min
Explanation:
Applying law of mass action for the given reaction:
Average rate = ![-\frac{1}{2}\frac{[N_{2}O_{5}]}{\Delta t}=\frac{1}{4}\frac{\Delta [NO_{2}]}{\Delta t}=\frac{\Delta [O_{2}]}{\Delta t}](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B2%7D%5Cfrac%7B%5BN_%7B2%7DO_%7B5%7D%5D%7D%7B%5CDelta%20t%7D%3D%5Cfrac%7B1%7D%7B4%7D%5Cfrac%7B%5CDelta%20%5BNO_%7B2%7D%5D%7D%7B%5CDelta%20t%7D%3D%5Cfrac%7B%5CDelta%20%5BO_%7B2%7D%5D%7D%7B%5CDelta%20t%7D)
Where, ![-\frac{1}{2}\frac{[N_{2}O_{5}]}{\Delta t}](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B2%7D%5Cfrac%7B%5BN_%7B2%7DO_%7B5%7D%5D%7D%7B%5CDelta%20t%7D)
represents average rate of disappearance of 
, ![\frac{1}{4}\frac{[NO_{2}]}{\Delta t}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%5Cfrac%7B%5BNO_%7B2%7D%5D%7D%7B%5CDelta%20t%7D)
represents average rate of appearance of 
and ![\frac{[O_{2}]}{\Delta t}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BO_%7B2%7D%5D%7D%7B%5CDelta%20t%7D)
represents average rate of appearance of 
Here,![-\frac{[N_{2}O_{5}]}{\Delta t}](https://tex.z-dn.net/?f=-%5Cfrac%7B%5BN_%7B2%7DO_%7B5%7D%5D%7D%7B%5CDelta%20t%7D)
= 
So average rate of reaction = ![[tex]-\frac{1}{2}\frac{[N_{2}O_{5}]}{\Delta t}](https://tex.z-dn.net/?f=%5Btex%5D-%5Cfrac%7B1%7D%7B2%7D%5Cfrac%7B%5BN_%7B2%7DO_%7B5%7D%5D%7D%7B%5CDelta%20t%7D)

Answer:
P₂ = 1102 Kpa
Explanation:
Given data:
Initial pressure = 1000.0 Kpa
Initial temperature = 20.0°C
Final temperature = 50.0°C
Final pressure = ?
Solution:
Initial temperature = 20.0°C (20+273 = 293 K)
Final temperature = 50.0°C (50+273 = 323 K)
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
1000 Kpa / 293 K = P₂/323 K
P₂ = 1000 Kpa × 323 K / 293 K
P₂ = 323000 Kpa. K /293 K
P₂ = 1102 Kpa
Answer:
<h2>D</h2>
Explanation:
<em>According to Universe Today, The answer is D because Radiation from the Sun, which is more popularly known as sunlight, is a mixture of electromagnetic waves ranging from infrared (IR) to ultraviolet rays (UV). It of course includes visible light, which is in between IR and UV in the electromagnetic spectrum.</em>

Coal is being formed from decayed fossils and remains. These materials are smashed, "compacted" together until their chemicals merge together from the pressure of the compacting this is also how diamonds form from coal just more heat and more pressure. This process is called compaction. Without such, no coal will be present.
