If the concentration of fluoride anion and aluminum cation was increased to 5M, then there would be decrease in Ecell by 0.055 volts
The standard reduction potential of Fluoride anion and aluminum cation are -
2Al -----> 2Al3+ + 6e- cell = +1.66
6e- + 3F2 -----> 6F- cell = +2.87
The complete reaction is -
2Al + 3F2 ------> 2Al3+ + 6F- = +4.53
Using Nernst Equation :-
E = – 0.0592/n*log[Al3+]^2[F-]^6
n = 6 (n = number of transferred electrons)
E = +4.53 - 0.0592/6*log(5)^2(5)^6
E = +4.53 - 0.00987*log(25)(1.56 x 10^4)
E = +4.53 – 0.00987*log(3.9 x 10^5)
E = + 4.53 -0.00987(5.59)
E = + 4.53 - 0.055
E = +4.47
The change in Ecell = 5 - 4.47 = 0.055V

<u>Answer:</u> The value of for the reaction at 550.3 K is 247.83
<u>Explanation:</u>
Equilibrium constant in terms of concentration is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
For a general chemical reaction:
The expression for is written as:
The chemical equation for the production of methanol follows:
The expression of for above equation follows:
We are given:
Putting values in above equation, we get:
