Some "beetles" defend themselves by spraying hot quinone, C6H4O2(l), at their enemies. Calculate rH° for this reaction.

C6H4(OH)2(l) + H2O2(l) → C6H4O2(l) + 2 H2O(l)
Given: C6H4(OH)2(l) → C6H4O2(l) + H2(g) +177.4 kJ/mol

The standard enthalpies of formation of H2O2(l) and H2O(l) are -187.4 and -285.8 kJ/mol, respectively.
◦ -206.8 kJ/mol
◦ -384.2 kJ/mol
◦ -561.6 kJ/mol
◦ +79.00 kJ/mol
