Question

If all the testube contains the same reactants, analyze the data given below regarding each of their concentrations and choose the correct option.


$\begin{array}{cc}\text{Test tube}& \text{Reactant concentration}\\ \text{A}& \text{2 mol/L}\\ \text{B}& \text{4 mol/L}\\ \text{C}& \text{8 mol/L}\\ \text{D}& \text{10 mol/L}\end{array}$

The rate of the reaction will be maximum in:

• A. Test tube A
• B. Test tube B
• C. Test tube C
• D. Test tube D

Answer 1

The correct option is D Test tube D

As the test tube D here has more concentration of the reactant, it has more number of reactant particles per litre as compared to the reactant solution in other three test tubes. Therefore, during the reaction, the number of collisions will be more in case of test tube D. So, the rate of the reaction will be highest in case of test tube D.
