Give the units the `K_(c)` for the formation of 1 mole of `NH_(3)` from its constituents .

Assertion : The enthalpy change for the reaction CaO_((s))+CO_(2(g)) rarr CaCO_(3(s)) is calld enthalpy of formation of calcium carbonate. Reason : The reaction involves formation of 1 mole of CaCO_(3) from its constituent elements.

The equilibrium constant K_(p) for the reaction, N_(2)+3H_(2) hArr 2NH_(3) is 1.64xx10^(-4) at 400^(@)C and 0.144xx10^(-4) at 500^(@)C . Calculate the mean heat of formation of 1 mol of NH_(3) from its elements in this temperature range.

K_(1),K_(2) and k_(3) for the complexation of SCN^(Θ) with Fe^(3+) are 130, 16, and 1.0 , respectively. (i) Calculate the overall formation costant of fe(SCN)_(3) from its constituent ions. (ii) Calculate K_(d) (dissociation constant) of Fe)SCN)_(3) .

What is the value of Delta n in the formation of acetaldehyde from its constituent elements?

If K_(c) for the formation of HI from H_(2) and I_(2) is 48, then K_(c) for decomposition of 1 mole of HI is _______.
