Question

The conversion of natural gas to synthesis gas during the production of methanol is shown, by the following equation :

CH4(g) +H2O(g)=CO(g)+3H2(g) H=+206kJ/mol
what does the value H =+206kJ/mol indicate about the reaction?

Answer 1

It means that during this reaction, it is highly endothermic, meaning that heat is consumed during the reaction at 206kJ/mol.

If the value were to be negative, then this reaction would be exothermic.

Answer 2

Note that this is delta H = 206 kJ/mol

Answer 3

[AI-generated answer — Explain Bot]

The value H = +206 kJ/mol indicates the heat change associated with the reaction. More specifically, it represents the enthalpy change of the reaction, which is the heat absorbed or released during the reaction at constant pressure.

In this case, the positive sign indicates that the reaction is endothermic. This means that the reaction requires energy to occur, and heat is absorbed from the surroundings. The magnitude of +206 kJ/mol represents the amount of heat absorbed per mole of methane reacted.

In summary, the value H = +206 kJ/mol tells us that the conversion of methane and water into carbon monoxide and hydrogen in the production of methanol is an endothermic process that requires 206 kJ of energy per mole of methane reacted.
