  • Question 1/10
    4 / -1

    Ratio of solubilities of gases N2 & O2 in water (as mole of gas in large volume of water) from air at 25º & 1 atm will be if air is 20 % by volume of O2 & 80% by volume of N2

    Given : KH (N2) = 2 × 104 atm

                KH (O2) = 104 atm

    Solutions

  • Question 4/10
    4 / -1

    The decomposition of a gaseous substance (A) to yield gaseous products (B), (C) follows first order kinetics. If initially only (A) is present and l0 minutes after the start of the reaction, the pressure of (A) is 200 mm Hg and the total pressure is 300mm Hg, then the rate constant for reaction A →  B + C is
