Given :
2NOBr(g) - -> 2NO(g) + Br2(g)
Initial pressure of NOBr , 1 atm .
At equilibrium, the partial pressure of NOBr is 0.82 atm.
To Find :
The equilibrium constant for the reaction .
Solution :
2NOBr(g) - -> 2NO(g) + Br2(g)
t=0 s 1 atm 0 0
1( 1-2x) 2x x
So ,
At equilibrium :
![K_{eq}=\dfrac{[NO]^2[br_2]}{[NOBr]^2}\\\\K_{eq}=\dfrac{0.18^2\times 0.9}{0.82^2}\\\\K_{eq}=0.043\ atm](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cdfrac%7B%5BNO%5D%5E2%5Bbr_2%5D%7D%7B%5BNOBr%5D%5E2%7D%5C%5C%5C%5CK_%7Beq%7D%3D%5Cdfrac%7B0.18%5E2%5Ctimes%200.9%7D%7B0.82%5E2%7D%5C%5C%5C%5CK_%7Beq%7D%3D0.043%5C%20atm)
Hence , this is the required solution .

Answer:
2.1 x 10^24 Cr ions
Explanation:
You need to multiply the 3.5 mol by the Avogrado's number (6.022 x 10^23) to get your answer.
Mass number<span> is found by adding the </span>number<span> of protons and </span>neutrons<span>.So </span>Fluorine<span>, which has </span>9 protons<span> would be added to the </span>number<span> of neutrons, </span>8<span>. Therefore, the mass number of fluorine would be 17. Hope this helps. Have a nice day.</span>
Answer:
Picking up marbles and placing them in a sack
Explanation:
The entropy of a chemical system is defined as the measure of disorder. Therefore a negative change in entropy is the movement to a more ordered state. The only option here which achieves a more ordered state, would be the first option.
Picking up marbles and placing them in a stack achieves more order, rather than the other options - that achieve more disorder.
