Question

The enthalpy change for the following reaction is -483.6 kJ:

2H2 (g) + O2 (g) → 2H2O (g)

Therefore, the enthalpy change for the following reaction is ____kJ.

4H2 (g) + 2O2 (g) → 4H2O (g)

Select one:

a.
2.34e5


b.
-967.2


c.
-483.6


d.
967.2


e.
483.6

Answer 1

what do you think it is

Answer 2

Enthalpy is an extensive property, which means it depends on the quantity of matter involved

Notice how the reaction coefficients all doubled, so the enthalpy should double as well
