Answer:
3.3 * 10^-12
Explanation:
The balanced equation of the reaction is;
2H+(aq) + Cu(s) ---------> H2(g) + Cu2+(aq)
Hence two electrons were transferred so n=2
E°cell = E°cathode - E°anode
E°cell = 0 V - 0.34 V
E°cell = - 0.34 V
Then;
E°cell = 0.0592/n log K
Substituting values;
- 0.34 = 0.0592/2 log K
- 0.34/0.0296 = log K
-11.486 = log K
K = Antilog (-11.486)
K = 3.3 * 10^-12
Answer: The concentration of 
will be 
after 416 seconds have passed.
Explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant = 
t = age of sample = ?
a = let initial amount of the reactant = 
a - x = amount left after decay process =
The concentration of will be after 416 seconds have passed.
I dont see any options to choose from but im pretty sure its the electron count that the elements have
