Answer:
K=1.93
Explanation:
Given reactions are:
A +2B ⇄ 2C K1=2.79
2C ⇄ D K2=0.186
D⇄ A+ 2B K=?
If we reverse the reaction then the euillibrium constant also become reciprocal of original value:
3rd reaction is a combination of reciprocal of 1st and 2nd reaction
2C⇄A +2B 1/K1;........................1
D ⇄ 2C 1/K2; ..............................2
On adding 1 and 2
D ⇄A +2B
K=1.93
When comparing the reactivity of aluminum or magnesium to the reactivity of silver, we will find that both aluminum and magnesium are more reactive than silver.
Therefore, magnesium or aluminum can both replace the silver in the silver sulphide.
That's why <span>a piece of aluminum or magnesium can be used to remove tarnish, which is mostly silver sulfide, on silverware.</span>
