Na2O + H2O + 170kj -> 2NaOHThe amount of heat energy absorbed per one mole of NAOH produced is ?

Answer 1

Hello, Srinivas,

Your equation

Na2O + H2O + 170kj -> 2NaOH

tells us that 170 kJ is absorbed during the formation of 2 moles of NaOH. Thus, the energy per mole of NaOH is 170kJ/2, or 85kJ/mole NaOH.
