Define the Ebullioscopic constant

Explanation

` Delta T_b =H_b m `
where `K_b` = molal boiling point elevation constant or Ebullioscopic constant .If m=1 then `Delta T_b =K_b : `
Hence , the `K_b` is equal to the elevation in boiling point for 1 molal solution .` K_b ` is calculated by the following expression
` K_b =( RT^(2) M_("solvent ")/(Delta H_("vapourisation ") ) `
