ΔH for the following reaction is -180 kJ. Is this reaction endothermic or exothermic? 2 Na(s) + 2 H2O(l) –> 2 NaOH(aq) + H2(g) Group of answer choicesexothermicendothermic

If the heat of reaction, that is the enthalpy change ΔH, for a certain process, is +32 kJ, that process Question 3Select one:a.occurs rapidlyb.is exothermicc.is endothermicd.cannot occure.requires a catalyst

∆H for the forward reaction is –92 kJ / mol.State why this value shows that the forward reaction is exothermic.

ΔH for the following reaction is -431 kJ. Is the reaction endothermic or exothermic? Ba(s) + 2 H2O(l) –> Ba(OH)2(aq) + H2(g) Group of answer choicesexothermicendothermic

find something that can help me solve the answer for An endothermic reaction has an activation energy of 95 kJ in the forward direction and an activation energy of 55 kJ in the reverse direction. Sketch the potential energy diagram and label the EA(Forward) , EA(Reverse) and determine and label the △HReverse. (5 marks)
