The rate of an irreversible reaction

Correct answer: A. increase with increase in concentration of the reactants

  • A. increase with increase in concentration of the reactants
  • B. Decreases with increase in concentration of the reactants
  • C. Increases with increase in concentration of the products
  • D. Decreases with increase in concentration of the products

Explanation

For an irreversible reaction, the rate of the reaction typically increases with an increase in the concentration of the reactants. This is because the rate of a reaction is directly proportional to the concentration of the reactants raised to their respective orders in the rate law equation.In an irreversible reaction, all reactants are converted into products, and once a reactant is consumed, it cannot be regenerated. Therefore, increasing the concentration of the reactants will result in more frequent collisions between reactant molecules, leading to an increase in the rate of the reaction

About Reaction Kinetics

Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
