In an elementary reaction, the number of atoms or ions which are colliding to react is known as molecularity. Had the reaction been of elementary nature (single step reaction) the order of reaction with respect should have been 1 but it is `3//2` i.e. fractional. This shows that the reactioin is of complex nature and is not elementary reaction.

For a reaction between gaseous compounds, `2A + B rarrC + D` , the reaction rate law is rate k[A][B]. If the volume of the container is made `1//4^(th

Correct Answer - C Concentration will increase by 4 times of each reactant `therefore ` Rate will become ` (4)^(2)` I .e 16 times

For a reaction : `A+B to` Products. The rate law expression is: rate = `k[A]^(1//3).[B]^(2)`. a) What is the order of the reaction? b) What are the un

a) The rate law epression is: Rate(r) = `k[A]^(1//3)[B]^(2)therefore` Order of reaction `=1/3 + 2=2(1/3)` b) Rate constant, k =`("rate")/([A]^(1//3)[B]^(2))` `therefore` Units of rate constant = `(moldm^(-3)s^(-1))/((mol dm^(-3^(1//3))(mol dm^(-3))^(2)))` `=(moldm^(-3))^(1-7//3)s^(-1)=(mol...

The rate of reaction: `2NO + Cl_(2) rarr 2NOCl` is given by the rate, equation rate `= k[NO]_(2)[Cl_(2)]`. The value of the rate constant can be incre

Correct Answer - A a) The value of rate constant depends upon temperature and not upon the initial concentration of reactants and products.
