Consider the given graph showing variation of reactant concentration with time.
Three different reactions were started with identical initial concentration of reactants. Which of the following statement is correct?
A
The order of all the three reactions is same.
B
The rate constant of reaction 3 is larger than the rate constant of reaction 2 if the order of reaction is same for both.
The SI unit of rate constant of reaction 1 is
.
The SI unit of rate constant of reaction 1 is
. C
Thermal decomposition of HI on gold surface is an example of reaction 2 .
Text Solution
Verified by ExpertsThe correct answer is:
B
⇒ Curve 
represent zero order kinetics
⇒
Reaction-1 is zero order having unit of rate constant same as rate of reaction i.e., molarity / second.
