B. Molecule is smallest possible part of any compound.
The calculation equation for density is density = mass / volume. So the density for this material is 52.457/13.5=3.886 g/cm3.
Answer:
1.78 M⁻²s⁻¹
Explanation:
Let's consider the following reaction:
A + B → C + D
The reaction order for A is 1 and the reaction order for B is 2.
The rate law is:
r = k.[A].[B]²
where,
r is the rate of the reaction
k is the rate constant
[A] and [B] are the molar concentrations of the reactants
Then, we can find the value of k.
