According to the decomposition of XY is second order, and we assume that the rate constant (K) = 6.92 X 10^-3 M^-1 :
So according to this formula:
Kt= 1/[XY]t - 1/[XY]o
when [XY]o is the initial concentration = 0.1 m & [XY]t is the concentration after passing a period of time= 0.1 x 0.125 = 0.0125 m
and when K= 6.92X10^-3 M^-1
By substitution:
t = (1/[XY]t - 1/[XY]o) / K
=(1/0.0125 - 1/0.1) / 6.92X10^-3
∴t = 1011 S = 17 min
Answer:
1 x 10^13 stadiums
Explanation:
We are given that;
1 stadium holds = 1 × 10^5 people
Number of iron atoms is 1 × 10^18 atoms
Assuming the stadium would carry an equivalent number of atoms as people.
Then, 1 stadium will carry 1 × 10^5 atoms
Therefore,
To calculate the number of stadiums that can hold 1 × 10^18 atoms we divide the total number of atoms by the number of atoms per stadium. Number of stadiums = Total number of atoms ÷ Number of atoms per stadium
= 1 × 10^18
atoms ÷ 1 × 10^5 atoms/stadium =
1 × 10^13 Stadiums
Thus, 1 × 10^18 atoms would occupy 1 × 10^13 stadiums
