When in danger, bombardier beetles can fire a hot, toxic mixture of chemicals at the attacker. This mixture contains quinone, CoH.O2, a compound that is formed by the reaction of hydroquinone, CoH4(OH)2, with hydrogen peroxide, H202. The reaction is catalysed by an enzyme called catalase. The equation for the overall reaction is: CoHa(OH)2(aq) + Hz2Oz(aq) → COH4O2(aq) + 2H20(1) Use the following data to calculate the enthalpy change, in kJ mol, for the above reaction. CoH«(OH)2(aq) CoH4Oz(aq) + H2(g) AH = +177.4kJ mol H2(g) + Oz(g) H2O2(aq) AH = -191,2kJ mol1 Ha(g) + 놀O2(g) H20(g) AH = -241.8kJ mol H20(g) H2O(1) AH = -43.8kJ mol1 %3D
