If the moles of HCl in container B are equal to five times the O2 present, what can be said about the moles of O2 present at equilibrium?

If the moles of HCl in container B are equal to five times the O2 present, what can be said about the moles of O2 present at equilibrium? Correct Answer It is impossible to determine

D-To determine the amount, it would be necessary to know the value of the equilibrium constant. A cannot be correct because it is not possible for the amount of any of the materials to be zero at equilibrium. B and C cannot be correct because at least some of the O2 would be converted to Cl2 and H2O leading to a decrease in the amount.

Compound A is extracted from a solution of A + B into a pure solvent S. A Co-current unit is used for the liquid-liquid extraction. The inlet rate of the solution containing A is 200 moles of B/hr.m2 and the solvent flow, rate is 400 moles of S/m2.hr. The equilibrium data is represented by Y = 3X2, where Y is in moles of a A/moles of B and X is in moles A/moles of S. The maximum percentage extraction achieved in the unit is

In the following question, 3 statements are given. You have to find which is/are necessary and sufficient to answer the following question. Two containers each contain some balls of Red and Blue color. Now all the balls of these two containers are mixed into a single third container which also contained some Red and Blue color balls initially as well. If 5 balls are taken out, then find the probability that all the balls taken out are Red in color. Statement 1∶ Total number of balls finally in 3rd container is 135. Statement 2∶ Ratio of balls in 1st container and 2nd container is 2 ∶ 7 Statement 3∶ Ratio of Red and Blue balls in 3rd container before mixing is 2 ∶ 3
