Given data:
Diameter of the gold wire (d) = 0.175 cm
Length of the gold wire (l) = 1.00 * cm
Volume of the given gold wire = volume occupied by a cylindrical object\
= π * *l
here r = radius of the cross section
where : r = d/2
Hence the volume V = π * *l
=
Density of gold = 19.3 g/cm3
Weight of the gold wire = Density * volume
= *
=
The rate law for the reaction : r=k.[A]²
<h3>Further explanation</h3>Given
Reaction
A ⟶ B + C
Required
The rate law
Solution
The rate law is a chemical equation that shows the relationship between reaction rate and the concentration / pressure of the reactants
For the second-order reaction it can be:
1. the square of the concentration of one reactant.
2. the product of the concentrations of two reactants.
And the reaction should be(for second order) :
2A ⟶ B + C
Thus, for reaction above (reactant consumption rate) :
