The value of ΔH° for the reaction below is -790 kJ. The enthalpy change accompanying the reaction of 0.95 g of S is kJ. 23 2S (s) + 3O (g) 2SO (g

The enthalpy change accompanying the reaction will be "-11.85 kJ".

Given:

Value of ΔH°,

According to the question,

→

Mol of S will be:

=

=

hence,

The enthalpy change for 0.03 mol will be:

=

=

Thus the answer above is correct.
