Question

Which of the following reaction will be occurring at a greater speed?

• A. Reactants reacting at 1 atm pressure
• B. Reactants reacting at 2 atm pressure
• C. Reactants reacting at 5 atm pressure
• D. Reactants reacting at 10 atm pressure

Answer 1

The correct option is D Reactants reacting at 10 atm pressure

Pressure is one of the factors which affects the rate of the reactions. On increasing the pressure of the gases the molecules come closer which inturn increases the number of molecules per unit volume. This result in increase in the number of collision of molecules which increases the rate of the reaction. Therefore, the speed of the reaction will be greater in the case of reactants reacting at 10 atm pressure.
