Analyze the diagram given below and identify in which test tube the rate of reaction will be maximum.
Test tube D
Pressure is one of the factors which affects the rate of the reaction. On increasing the pressure of the gases the molecules come closer which further increases the number of molecules per unit volume. As a result, the number of collision of molecules increases which increases the rate of the reaction.
Therefore, the speed of the reaction will be greater in the case of reactants reacting at 5 atm pressure i.e. in test tube D.
