Answer:
a) 1,737 kJ
b) -1,93 kJ
Explanation:
The standard free energy change (ΔG) can be determined using:
ΔG = -nFE
a) For the reaction:
Fumarate²⁻ + CoQH₂ ⇄ succinate²⁻ + CoQ
The transferred electrons are 2, As E=-0,009V:
ΔG = -2×96,5kJ/molV×-0,009V
<em>ΔG = 1,737 kJ</em>
b) For the reaction:
cytc1 (Fe²⁺) + cytc (Fe³⁺) ⇄ cytc1 (Fe³⁺) + cytc (Fe²⁺)
The transferred electron is n=1 and E=0,02V:
ΔG = -1×96,5kJ/molV×0,02V
<em>ΔG = -1,93 kJ</em>

Answer:
See explanation
Explanation:
According to the law of conservation of mass; the total mass of reactants on the left hand side of the reaction equation is equal to the total mass of products on the right hand side of the reaction equation.
Hence, the total mass of each atom on either side of the reaction equation should be exactly the same.
Since there are two atoms of oxygen on the reactants side, the total mass of oxygen = 16 amu * 2 = 32 amu
Since there are two oxygen atoms on the products side, total mass of oxygen = 16 amu * 2 = 32 amu
