A decomposer is not a disturbance of the ecosystem because it decomposes dead animal bodies and recycles it into the soil which helps the food chain work
Answer: The standard cell potential (E∘) for the reaction
is -0.121 V
Explanation:
The reaction is:
Relation between standard Gibbs free energy and equilibrium constant follows:

where,
= Standard Gibbs free energy = ?
R = Gas constant = 
T = temperature = 298 K
K= equilibrium constant = 
Putting values in above equation, we get:

To calculate standard Gibbs free energy, we use the equation:

Where,
n = number of electrons transferred = 1
F = Faradays constant = 96500 C
= standard cell potential = ?
Putting values in above equation, we get:



Thus standard cell potential (E∘) for the reaction
is -0.121 V
