OK. You changed screen names BUT you also included units.
Then heat is added delta H is +. When heat is produced, delta H is -.
So for this _+2.4 kcal is delta H.
How do I determine the value of the reaction
2HI(g) + 2.4 kcal --> H2(g) + i2(g)
delta H =
a) 2.4 kcal
b) -2.4 kcal
c) 0.00024 kcal
d) -0.00024 kcal
