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.
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?

Note that this is delta H = 206 kJ/mol
