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) :
There are 8.786 g
<h3>Further explanation </h3>The mole is the number of particles contained in a substance
1 mol = 6.02.10²³
2.30 x 10²³ atoms in Na :
mass :
