3. Given that AH =-622.2kJ N,H., +02: H4+503, »N,, +24,0, H40, AH =-285.8kJ Determine the heat of reaction for: N2g +2H,, ->N

Answer 1

Answer #1

Gwen & ANSWER Nathaw + 02 19 H2 49 + 10 - A Nz (q) + 2 H2O H2O 4 - (2) (1) AH = -622 . QUI AH = -285.8 kJ 0 wnluq Determining Answer = 50.6 kJ

The reaction is Endothermic.

Reason-

As the enthalpy is positive and Delta H is greater than 0, this means the system has absorbed heat which is therefore called as endothermic reaction.
