So im wondering if the molar standartreactionenthalpy is refering to 1 mol of created or used substance or if its on 1 time the the equasion. And if the second one would be the case, if i would need to be careful with translating it into the standartreactionenthalpy like when given a certain amount of mol product like in the picture H2O would i have to calculate it with 5mol instead of 10 because in the molar standartreactionenthalpy its already calculated for 2 mol water. Sorry if its a Dumb question or hard to understand.
