One mole of a reactant reacts with a rate of 0.6 mol dm-3 s-1. What is the rate cost of this reaction?
Correct answer: C. 0.6 s-1
- A. 1 s-1
- B. 0.3 s-1
- C. 0.6 s-1
- D. 0.9 s-1
Explanation
The rate of a reaction is typically expressed in terms of moles per unit volume per unit time. In this case, the rate is given as 0.6 mol dm-3 s-1, which means that 0.6 moles of the reactant are reacting per decimetre cubed per second.Since one mole of the reactant is reacting at this rate, it means that one mole of reactant will react in one second. Therefore, the correct answer is:C. 0.6 s-1Options A, B, and D are incorrect because they do not accurately represent the given 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.
