Calculate DeltaH (in kcal) for the following phase transformation : A (s,1 bar, `200`K) rarr A (g, `1` bar ,`200` K) Standard melting poing of A = `200` K Standard boioling poing of A = `300 K` Standard boiling ping of A = `300` K Latent heat of fusion of A at `200` K = `60 cal//g` Latent heat of vaporisation of A at `300 K = 410 cal//`g Molar mass of A = `50 g//`mole `C_(Vm)` of A (s)= 5cal `K^(-1)` `mol^(-1)` `C_(Vm)` of A (l) = `10 cal K^(-1)mol^(-1)` `C_(Vm)` of A (g)=`3cal K^(-1) mol^(-1)` `R=2 cal K^(-1) mol^(-1)` |
