Which of the following is true for a reaction when AG is a positive value? A) The reverse of the reaction is spontaneous B) The
Papessa [141]

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.

When nitrogen dioxide (NO2) from car exhaust combines with water in the air, it forms nitric acid (HNO3), which causes acid rain
Gekata [30.6K]

Answer:

n_{HNO_3}=0.584molHNO_3

Explanation:

Hello.

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

NO_2+H_2O\rightarrow HNO_3

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

3NO_2+H_2O\rightarrow 2HNO_3+NO

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:

n_{HNO_3}=0.292molH_2O*\frac{2molHNO_3}{1molH_2O}\\\\ n_{HNO_3}=0.584molHNO_3

Best regards!
