Assertion: If `H_(2)` and `Cl` enclosed separately in the same vessel exert pressure of `100` and `200 mm` respectively, their mixture in the same vessel at the same temperature will exert a pressure of `300 mm`
Reason: Dalton's law of partial pressures states that total pressure is the sum of partial pressures.

Options

A. If both (`A`) and (`R`) are correct and (`R`) is the correct explanation of (`A`).
B. If both (`A`) and (`R`) are correct, but (`R`) is not the correct explanation of (`A`).
C. If (`A`) is correct, but (`R`) is incorrect.
D. If (`A`) is incorrect, but (`R`) is correct.

Answer

A, B, C, D

Explanation

`P_(total)=P_(1)+P_(2)+P_(3)+…`
Partial pressure `=x xx P_("total")`
where `x=` mole fraction
