Answer:
The value of is 0.02495.
Explanation:
Initial concentration of gas = 0.675 M
Initial concentration of gas = 0.973 M
Equilibrium concentration of mustard gas = 0.35 M
initially
0.675 M 0.973 M 0
At equilibrium ;
(0.675-0.35) M (0.973-2 × 0.35) M 0.35 M
The equilibrium constant is given as :
The relation between and are :
where,
= equilibrium constant at constant pressure = ?
= equilibrium concentration constant =14.45
R = gas constant = 0.0821 L⋅atm/(K⋅mol)
T = temperature = 20.0°C =20.0 +273.15 K=293.15 K
= change in the number of moles of gas = [(1) - (1 + 2)]=-2
Now put all the given values in the above relation, we get:
The value of is 0.02495.
Recrystallization is a separating technique in chemistry in which mixtures are dissolve in appropriate solvent, this leads to the separating out of one of the components of the mixture leaving behind the other component. The technique is used to purify solid substances.
In real life, the technique finds application in re-crystallization of metals.
Sorry I don't know I would help but I'm only good at social study's and hystory and geography
The ice<span> cube which was solid has turned into the liquid water because the air temperature is warmer than the freezers. Which means the </span>ice<span> particles gather heat energy from the warmer air. Therefore the </span>ice<span> particles have enough energy to break apart (</span>melt<span>)into smaller particle arrangements.</span>
