Answer:
24 hours
Explanation:
The computation is shown below:
The needed mole of is
= 5 ÷22.4 = n
Also 1 mole of required four electric charge
Now the charge needed is
= n × 4 × 96,500 C
= 4 × 96,500 × 5 c ÷ 22.4
= 86160.714 C
Now
q = i t
t = q ÷ i
= 86160.714 C ÷ 0.995
= 86593.7 seconds
= 24 hours
Hence, the correct option is A.
<u>Answer:</u> The equilibrium concentration of chlorine gas, fluorine gas and ClF gas is 0.159 M, 0.317 M and 1.002 M respectively.
<u>Explanation:</u>
We are given:
Initial concentration of chlorine gas = 0.307 M
Initial concentration of fluorine gas = 0.465 M
Initial concentration of ClF gas = 0.706 M
The given chemical equation follows:
<u>Initial:</u> 0.307 0.465 0.706
<u>At eqllm:</u> 0.307-x 0.465-x 0.706+2x
The expression of for above equation follows:
We are given:
Putting values in above equation, we get:
Neglecting the value of x = 0.993 because the equilibrium concentrations of chlorine and fluorine gases will become negative, which is not possible
So, equilibrium concentration of chlorine gas = (0.307 - x) = [0.307 - 0.148] = 0.159 M
Equilibrium concentration of fluorine gas = (0.465 - x) = [0.465 - 0.148] = 0.317 M
Equilibrium concentration of ClF gas = (0.706 + 2x) = [0.706 + 2(0.148)] = 1.002 M
Hence, the equilibrium concentration of chlorine gas, fluorine gas and ClF gas is 0.159 M, 0.317 M and 1.002 M respectively.
