Answer:
The formula of acceleration is final velocity-initial velocity÷time taken
Explanation:
v-u/t
Answer:
The reaction is not at equilibrium and reaction must run in forward direction.
Explanation:
At the given interval, concentration of NO = ![\frac{4.64\times 10^{-2}}{1}M=4.64\times 10^{-2}M](https://tex.z-dn.net/?f=%5Cfrac%7B4.64%5Ctimes%2010%5E%7B-2%7D%7D%7B1%7DM%3D4.64%5Ctimes%2010%5E%7B-2%7DM)
Concentration of
= ![\frac{4.56\times 10^{-2}}{1}M=4.56\times 10^{-2}M](https://tex.z-dn.net/?f=%5Cfrac%7B4.56%5Ctimes%2010%5E%7B-2%7D%7D%7B1%7DM%3D4.56%5Ctimes%2010%5E%7B-2%7DM)
Concentration of NOBr = ![\frac{0.102}{1}M=0.102M](https://tex.z-dn.net/?f=%5Cfrac%7B0.102%7D%7B1%7DM%3D0.102M)
Reaction quotient,
, for this reaction =
species inside third bracket represents concentrations at the given interval.
So, ![Q_{c}=\frac{(0.102)^{2}}{(4.64\times 10^{-2})^{2}\times (4.56\times 10^{-2})}=106](https://tex.z-dn.net/?f=Q_%7Bc%7D%3D%5Cfrac%7B%280.102%29%5E%7B2%7D%7D%7B%284.64%5Ctimes%2010%5E%7B-2%7D%29%5E%7B2%7D%5Ctimes%20%284.56%5Ctimes%2010%5E%7B-2%7D%29%7D%3D106)
So, the reaction is not at equilibrium.
As
therefore reaction must run in forward direction to increase
and make it equal to
.
Any substance changes to another substance that means the change of the physical property. Like water () has different state which changes as the temperature changes. It remain as liquid in the room temperature, in solid form at or below 0°C and vapor phase on or above 100°C. But in all the stage or phase of the substance the composition of the water i.e. remains. Thus the chemical property remains fixed when a substance change to other substance.
N2 + 3H2 --> 2NH3
Answer: 6 moles of hydrogen are needed to react with two moles of nitrogen.
