Consider the following statement "the more negative the value of Delta H(f), the more stable the compound." Is this statement true or false? Explain.
**the (f) is supposed to be a subscript in Delta H(f)
**the (f) is supposed to be a subscript in Delta H(f)
-
False, the stability doesnt matter whether Delta H is negative or positive

the reverse of the formation reaction describes how readily the compound decomposes into its elements. what this means is this: if the ∆Hf is -10kJ/mole then it takes the input of 10kJ/mole to decompose the compound to it's elements.
if ∆Hf is -20kJ/mole, it will take the input of 20kJ/mole to decompose the compound to its elements. so, yes, the lower the number of ∆Hf, the more stable it is because it will take more energy to break the bonds of the compound to its elements.
