Crysocopic and Ebullioscopic

The lowering ΔT_fus,A = |T^*_fus,A − T_fus,A| of the freezing temperature T^*_fus,A of a mass m_A of the solvent substance A by a dissolved amount n_B of solute substance B is given by the formula:

ΔT_fus,A = (n_B/m_A)T^*_fus,A(RT^*_fus,A/Δ¹_sh^*_A) = (n_B/m_A)k_fus,A,

where R denotes the gas constant (R = 8.314 51 J·K⁻¹· mol⁻¹), Δ¹_sh^*_A denotes the massic (formerly ‘specific’) enthalpy of fusion of the pure (*) solvent A, and k_fus,A is called the cryoscopic constant of A, and where it has been assumed that the solution is ideal-dilute and that the solid phase is that of the pure solvent.
Similarly, the corresponding elevation ΔT_vap,A = |T_vap,A − T^*_vap,A| of the boiling temperature at a given pressure is given by the formula:

ΔT_vap,A = (n_B/m_A)T^*_vap,A(RT^*_vap,A/Δ₁^gh*_A) = (n_B/m_A)k_vap,A,

where Δ₁^gh^*_A is now the massic enthalpy of evaporation of the pure solvent A and k_vap,A is called the ebullioscopic constant of A, and where it has been assumed that the solution is ideal-dilute and that the solute B is involatile.

Something i dun understand about these 2 constants in chemistry. I guess this explains it all
