Question

For the combustion reaction at 298 K

2Ag(s) + O2(g) -----> 2Ag2O(s)

Which of the following relation will be true ?

(1) ΔΗ = ΔΕ
(3) ΔΗ < ΔΕ
(2) ΔΗ > ΔΕ
(4) ∆H and ∆E bear no relationship with each other

please explain Ur option ​

Answer 1

second one is the correct answer

Answer 2

Answer:

ANSWER IS 2^^

Explanation:

becoz we know delta H is delta E plus ngrt

now find ng which is moles of gases in product side  minus moles of gases in reactant side

it comes out to be -3

so actually we get delta H is delta E minus 3RT

SO  uh know by mentally we can make out that delta E will be greater than delta H.
