Answer:

e. adiabatic process

Explanation:

Adiabatic process  -

In the thermodynamic system , an adiabatic process is the one which involves no transfer of mass or heat of the substance , is referred to adiabatic process.

In this process , the temperature need not be constant ,

But only the heat is transferred into or out of the system .

Hence, from the given information of the question,.

The correct option is e. adiabatic process .

Given the partial equation: NO3− Pb2 → NO2 Pb4 , balance the reaction in acidic solution using the half-reaction method and fill
Fed [463]

Answer : The balanced reaction in acidic solution is,

2NO_3^-+1Pb^{2+}+4H^+\rightarrow 2NO_2+1Pb^{4+}+2H_2O

Explanation :

The given partial equation is,

NO_3^-+Pb^{2+}\rightarrow NO_2+Pb^{4+}

First we have to separate into half reaction. The two half reactions are:

NO_3^-\rightarrow NO_2

Pb^{2+}\rightarrow Pb^{4+}

Now we have to balance the half reactions in acidic medium, we get:

NO_3^-+2H^++1e^-\rightarrow NO_2+H_2O       ............(1)

Pb^{2+}\rightarrow Pb^{4+}+2e^-     ............(2)

Now we have to balance the electrons of the half reactions. When we are multiplying the equation (1) by 2, we get

2NO_3^-+4H^++2e^-\rightarrow 2NO_2+2H_2O  ...........(3)

Now we have to add both the half reactions (2) and (3), we get the final balanced chemical reaction.

2NO_3^-+1Pb^{2+}+4H^+\rightarrow 2NO_2+1Pb^{4+}+2H_2O
