If rate of reaction = concentration of reactants x rate constant,
and rate constant = concentration of products/concentration of reactants,
then, is rate of reaction= concentration of products?
 
This is sooooooo confusing!! Please help me understand!

Thanks for asking us a question in Ask the Expert section of TopperLearning.com.

According to law of mass action, the rate of a chemical reaction is directly proportional to the product of effective concentrations of reacting species, each raised to a suitable power may or may not be equal to the respective stoichiometric coefficients.
nA ------> Products
Therefore rate of reaction = dx/dt = K[A]n
where K is rate constant.
Hence rate of reaction is not equal to concentration of products but it is equal to product of effective concentration of ractants.
