A mixture of two moles of hydrogen and one mole of argon gas is
taken in a closed container at room temperature. Consider the following
two statements
(i) The average kinetic energy of each molecule of H2 and Ar are the
same.
(ii) The partial pressure due to argon gas is more than that due to
hydrogen gas.

ABoth statement (i) and (ii) are correctBStatement (i) is correct while statement (ii) is incorrectCBoth statement (i) and (ii) are incorrectDStatement (i) is incorrect while statement (ii) is correct

Kav = [IMAGE] kT
Kav = [IMAGE] kT
p1 = [IMAGE] × p
n1 > n2 ⇒ p1 > p2
