Answer & explanation
Correct answer: option 2
A. Order of complex reaction is determined by Order of slowest step.
As complex reaction is a multistep reaction in which the rate of reaction will depend mostly on the slowest step. Hence, order of reaction is also determined by the slowest step.
B. Rate of zero order reaction is equal to Rate constant.
Consider a zero-order reaction, A → Products
Rate of reaction = k [A]0 = k (rate constant)
C. Relationship between rate of reaction and concentration of reactants is known as Rate Law.
aA + bB → cC + dD
Rate law = k [A]m [B]n where m and n are respective order w.r.t A and B determined experimentally.
D. Rate at particular moment of time is known as Instanteous rate.
Rate = \(\frac{dC}{dt}\)
where dC is small change in concentration in small time interval dt.
