Consider the chemical reaction, N _(2) (g) + 3 H _(2)(g) to 2 NH _(3) (g). The rate of this reaction can be expressed in terms of time derivative of concentration of N _(2) (g), H _(2) (g) or NH _(3) (g). Identify the correct relationship amongest the rate expression.

Indicate the correct statement for equal volumes of N_(2)(g) and CO_(2)(g) at 25^(@)C and 1 atm.

Calculate the volume of 4.4 g of CO_2 at S.T.P.

For the reaction H_(2)(g)+CO(g)hArrCO(g)+H_(2)O(g), if the initial concentration of [H_(2)]=[CO_(2)] and x moles /litres of hydrogen is consummed at equilibrium , the correct expression of K_(p) is :

Find the molarity and molality of a 14% solution of H_(2) SO_(4) by weight. The density of the solution is 1.10 g/cc and the molecular mass of sulphuric acid is 98
