A boy found a solid metal box in his backyard. The box had been buried for so long, it was difficult to determine from what the
box was made. The boy measured the box and found its volume (v) to be 17.63 cubic centimeters (cm3) and its mass (m) to be 158 grams (g). The boy knows the formula for density (D) is D = m/v. This table shows the density of several metals. DENSITY OF METALS *

Explanation:
(a) As the given chemical reaction equation is as follows.
So, when we double the amount of hypochlorite or iodine then the rate of the reaction will also get double. And, this reaction is "first order" with respect to hypochlorite and iodine.
Hence, equation for rate law of reaction will be as follows.
Rate =
(b) Since, the rate equation is as follows.
Rate =
Let us assume that ()
Putting the given values into the above equation as follows.
K =
=
Hence, the value of rate constant for the given reaction is
.
(c) Now, we will calculate the rate as follows.
Rate =
=
=
Therefore, rate when M and
M is
.
