Answer:
1. Not to have enough salt water on the foil
2.not cleaning the foil well to remove interfering materials
Over 344.76 K the forward reaction will be spontaneous
<u><em>calculation</em></u>
ΔG = ΔH° -TΔs
if ΔG =0
therefore 0 =ΔH°-TΔs
ΔH° = TΔs
divide both side by Δs
T = ΔH°/Δs
convert 34.2 kj into j
that is 1 kj = 1000 j
34.2 kj =? j
<em>by cross multiplication</em>
=[34.2 kj x 1000j / 1 kj] = 34200 j
T is therefore = 34200 j÷99.2 j/k =344.76 k
if T is greater than 344.76 k the forward reaction will be spontaneous
