Predict the sign and magnitude of AH, and determine whether the reaction is expected to be endothermic or exothermic. Select
all that apply.
AH-(285+368)-(397+193)-+63 kJ/mol
AH-(285-368) + (397-193)-+ 121 kJ/mol
The reaction is exothermic.
The reaction is endothermic.
AH-(397 +193)-(285+368)--63 kJ/mol
AH-(193-397)+(368-285)--121 kJ/mol
