Explanation:
We take activities of Solids and liquids equal 1. The reason is there concentrations not at all change amount of reactant at equilibrium in the reaction. Hence we don't consider concentrations of pure solids and liquids while writing equilibrium constant.
So for above reaction, equilibrium constant (K) = [Sn^2 +] ^3 x 1 / [Fe^3+]^2 x 1. Ping me if you have any doubts.
<u>Answer:</u> The pressure that the gas exert at high temperature is 9.63 atm
<u>Explanation:</u>
To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
![P_1=5.0atm\\T_1=76^oC=[76+273]K=349K\\P_2=?\\T_2=399^oC=[273+399]K=672K](https://tex.z-dn.net/?f=P_1%3D5.0atm%5C%5CT_1%3D76%5EoC%3D%5B76%2B273%5DK%3D349K%5C%5CP_2%3D%3F%5C%5CT_2%3D399%5EoC%3D%5B273%2B399%5DK%3D672K)
Putting values in above equation, we get:
Hence, the pressure that the gas exert at high temperature is 9.63 atm
