The enthalpy change for the reaction of titanium metal with gaseous iodine is given by the following thermochemical equation: 2
julia-pushkina [17]

Answer : The enthalpy change for the reaction is, 419.5 kJ

Explanation :

According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.

The given chemical reaction is,

2Ti(s)+3I_2(g)\rightarrow 2TiI_3(s)    \Delta H=-839kJ

Now we have to determine the enthalpy change for the reaction below:

TiI_3(s)\rightarrow Ti(s)+\frac{3}{2}I_2(g)    \Delta H'=?

By reversing and then dividing the reaction by 2, we get the enthalpy change for the reaction.

The expression will be:

\Delta H'=-\frac{(\Delta H)}{2}

\Delta H'=-\frac{(-839kJ)}{2}

\Delta H'=419.5kJ

Therefore, the enthalpy change for the reaction is, 419.5 kJ
