Determine the direction in which the following reaction is spontaneous at 25oc: mg2+(aq) + k(s) < > mg(s) + k+(aq) determine the equilibrium constant k and go using the cell potential for this reaction and which will be the anode and cathode?

The and of the reaction is and -108080 J respectively.

Explanation:

For the given cell reaction:

The half reaction follows:

Oxidation half reaction:

Reduction half reaction:

Oxidation reaction occurs at anode and reduction reaction occurs at cathode.

To calculate the of the reaction, we use the equation:

Putting values in above equation, we get:

where,

= Standard Gibbs free energy of the reaction = ?

n = number of electrons exchanged = 2

F = Faraday's constant = 96500

= standard electrode potential of the cell = 0.56 V

Putting values in above equation, we get:

R = Gas constant = 8.314 J/K.mol

T = temperature of the reaction =

= equilibrium constant of the reaction = ?

Putting values in above equation, we get:

Hence, the and of the reaction is and -108080 J respectively.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
