Question

. The standard enthalpy of formation of bis(benzene)chromium is measured in a calorimeter. It is found for the reaction

Cr(C6H6)2(s)→Cr(s)+2 C6H6(g) that ∆U

0

r

(583K)=8 kJ mol−1

. Find the corresponding reaction enthalpy and calculate standard

enthalpy of formation of the compound at 583 K. The constant pressure molar heat capacity of benzene is 136.1 JK−1mol−1

in

its liquid range and 81.67 JK−1mol−1

as a gas.​

Answer 1

Answer:

The constant-pressure molar heat capacity of benzene is 136.1 JK-1mol-1

liquid range, and 81.67 JK-1mol-1

range considered. The boiling point of benzene is 353 K.

as a gas; they are both considered constant over the temperature
