2A+B⇌2C+2DΔH∘rxn =319 kJ For the reaction given, how much heat is absorbed when 2.60mol of A reacts?A-269B-425C183D-505?
For the equilibrium reaction represented by the equation (2A + B \rightleftharpoons 2C + 2D) with a standard reaction enthalpy of (\Delta H^\circ_{\text{rxn}} = 319 \, \text{kJ}), how much heat is absorbed when 2.60 moles of reactant A are consumed?
Is it: A) 269 kJ B) 425 kJ C) 183 kJ D) 505 kJ?
