Decomposition of non-volatile solute 'A' into another non-volatile solute B and C, when dissolved in water follows first order kinetics as :
`A to 2B + C `
when one mole of A is dissolved in 180 gm of water and left for decomposition, the vapour pressure of solution was found to be 20 mm Hg after 12 hrs. Determine the vapour pressure of the solution (in mm of Hg) after 24 hars Assume constant temperature of `25^(@) C,` throughout . The vapour pressure of pure water at `25^(@) C ` is 24mm Hg.
