When the bomber beetle feels threatened, it blasts its enemy with an aqueous mixture of hydrogen peroxide (H2O2) and hydroquinone (C6H6O2) which react according to the following equation.

C6H6O2 (aq) + H2O2 (aq) C6H4O2 (aq) + 2 H2O (l) ∆H = -203.0 kJ / mol of C6H6O2 (aq)

Before the reaction begins, the concentration of hydroquinone is 1.50 mol / L and the mixture is at a temperature of 20.0 ° C.
If the beetle throws 5.00 ml of the mixture onto an enemy insect, what is the temperature of the liquid reaching that insect?

1)72.7 ° C

2)92.7 ° C

3)20.0 ° C

4)52.7 ° C
