Recap - Speed Trials

Part of the Energy, Rates and Equilibrium section of Coddy's Chemistry journey. Lesson 20 of 35.

Challenge

In a race between catalysts, hydrogen peroxide with powdered manganese dioxide gives $0.02\ \mathrm{mol}$ of oxygen in $40\ \mathrm{s}$ . What is its average rate $r$ in moles per second?

Try it yourself

Solve for $r$
