question_answer 1)

For the reaction RP, the concentration of a reactant changes from 0.03 M to 0.02 M in 25 minutes. Calculate the average rate of reaction using units of time both in minutes and seconds.

Answer:

Initial conc. = 0.03 M Final conc. = 0.02 M Decrease in conc., x = 0.03 ? 0.02 = 0.01 M Time taken for this change = 25 min Average rate = 6.66 × 10?6 M s?1
