Expert Answer

Given:

ΔH_rec = (-285.76)

We have,

ΔH subscript 373 space equals space increment straight H subscript 298 space plus space integral subscript 298 superscript 373 nC subscript straight p increment straight T ΔH subscript 373 space equals space minus 285.76 space plus space integral subscript blank superscript blank 75.312 space minus 38.83 space minus fraction numerator 29.16 over denominator 2 end fraction space space space space space space space space space space equals negative 285760 plus 21.902 space open parentheses 75 close parentheses space space space space space space space space space space equals space minus 285760 space space space space space space space space space space equals space minus 284117.35 space straight J ΔH subscript 373 space equals negative 284.11 space kJ

The value of Δ_fH at 373 K is −284.11 kJ.
