Answer:
A) The reverse of the reaction is spontaneous
Explanation:
Spontaneous means those reaction which occur own their own or just need an initiation. As we know that,
∆G = ∆H-T∆S,
A reaction is spontaneous if ∆G Comes out to be negative . Because only those reactions occur in which either ∆H ( enthalpy change) is negative or ∆S (entropy change) is positive or both condition satisfied , as if in a reaction, let
A + B ------> B + C
If ∆G is positive when reaction proceed in forward direction, i.e. , it means it will be negative if proceed in backwards direction i.e on reactants side . Which means for such reaction backwards reaction is spontaneous.
Explanation:
I think the answer is B ♂️ but I'm not sure
Answer:

Explanation:
Hello.
In this case, given the described reaction, the formation of nitric acid turns out:

Since two hydrogen atoms are present at the reactants we balance it as follows:

In such a way, since there is a 1:2 mole ratio between water and nitric acid, the produced moles of nitric acid, turns out:
