Nata [24]

Option B is correct

K = Kp /Kr

The given equation indicating, the product containing 6 moles of proton whereas the reactant contains 2 mole of bismuth and 3 mole of hydrogen sulphide.

Hence, in reaction B there are 2 mole of bismuth and 3 mole of hydrogen sulphide reacting to produce 6 moles of proton. whereas the concentration of Bi2S3 is not considered as it is present in solid phase.

In a mixture of 2 ideal gases, A and B, PA = 0.2PB, what is the mole fraction of A?
Alborosie

Answer:

0.1667

Explanation:

Hello,

Dalton's law defines:

y_i=\frac{P_i}{P_T}

A total pressure is:

P_T=P_A+P_B

So, for A (solving for P_A in the previous equation, we get:

y_A=\frac{P_A}{P_A+P_B}

Since P_A=0.2P_B, we obtain:

y_A=\frac{P_A}{P_A+P_A/0.2}\\y_A=\frac{1}{6}\\y_A=0.1667}

Best regards.
