Q. Brebuerat

2

aypr

()

sulfide macts with sulfur to produce copper (II) sulfide at

25^{\circ}C

. The process is exothermic

\Delta H^{\circ}:

yv calcylatite

16^{\circ}

,

\newline

\text{Cu}_\text{s}(\text{s})+\text{S}(\text{s})\rightarrow 2\text{Cu}_\text{s}(\text{s})

Identify Reaction and Data: Identify the chemical reaction and the given data. $\newline$ The reaction is $\text{Cu}_2\text{S(s)} + \text{S(s)} \rightarrow 2\text{CuS(s)}$ . The reaction is exothermic with $\Delta H = -16 \, \text{kJ}$ .
Write Enthalpy Change: Write down the enthalpy change for the reaction. $\newline$ Since the reaction is exothermic, the enthalpy change ( $\Delta H$ ) is negative, indicating that heat is released. $\Delta H = -16 \, \text{kJ}$ .
Confirm Units and Values: Confirm units and values. Check that the units are consistent ( $\text{kJ}$ ) and the value matches the problem statement.
