Answer: Rate of decomposition of acetaldehyde in a solution is [tex]1.45\times 10^{-14}mol/Ls[/tex]
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
For a reaction : [tex]A\rightarrow products[/tex]
[tex]Rate=k[A]^x[/tex]
k= rate constant
x = order of the reaction = 2
[tex]Rate=4.71\times 10^{-8}L/mol/s\times {5.55\times 10^{-4}M}^2[/tex]
[tex]Rate=1.45\times 10^{-14}[/tex]
Thus rate of decomposition of acetaldehyde in a solution is [tex]1.45\times 10^{-14}mol/Ls[/tex]
