It is known that wax contracts on solidification. If molten wax is taken in a large vessel and it is allowed to cool slowly, then

For a reaction X+Y = 2Z , 1.0 mo of X 1.5 mol of Y and 0.5 mol of Z where taken in a 1L vessel and allowed to react . At equilibrium , the concentration of Z was 1.0 mol L^(-1) . The equilibrium constant of the reaction is _____ (x)/(15) . The value of x is _____.

A disc rotates horizontal at the rate of 100 rpm and M.I. of the disc about the axis of rotation is 1 kg m^2 . If a blob of molten wax weighing 50 gm drops gently at a distance 20 cm from the axis of rotation of the disc and remains stuck to it, then the increase in moment of inertia of the system will be

A mixture of 0.5 mole of CO and 0.5 mole of CO_(2) is taken in a vessel and allowed to effuse out through a pinhole into another vessel which has vacuum If a total of A mole has effused out in time t show that M_(1)A +M_(2) (1-A) =36 where M_(1) and M_(2) are mean molar masses of the mixture that has effused out and the mixture still remaining in vessel respectively .

A sphere of outer radius R having some cavity inside is allowed to roll down on an incline. The incline is then made smooth by waxing and the sphere is allowed to slide without rolling and now the speed attained is (5//4)v_0 . What is the radius of gyration of the sphere about an axis passing through its centre ?
