Following reaction occurs in the given electrochemical system:
→ Fe +
Thus, under standard conditions
E(0) = E(0) Fe2+/Fe - E(0) Zn2+/Zn
where,
= standard reduction potential of Fe2+/Fe = -0.44 v
= standard reduction potential of Zn2+/Zn = -0.763 v
E(0) = 0.323 v
now, we know that, ΔG(0) =-nFE(0) ............... (1)
Also, Δ
On equating and rearranging equation 1 and 2, we get
K = exp(
)= exp (
) = 8.46 x
does it mean the reaction was exothermic (I am not too sure but that's what I think)
• a fuel gas consisting mainly of carbon monoxide and hydrogen, made by passing steam over incandescent coke
• the cranium and the mandible.
hope it helps...!!!
Explanation:
By placing the jar under hot water, metal lid molecules expanded from heat which caused it loosen up. However, there can be a possibility where the jar lid was stuck because of the stickiness of the pickle juice which later got washed off or melted after placing the jar under hot water.
