The decomposition of hydrogen peroxide to form water and oxygen in the presence of an iodide catalys — Kinetics Chemistry Question

The decomposition of hydrogen peroxide to form water and oxygen in the presence of an iodide catalyst is studied, and the rate law is found to be Rate = k[H₂O₂][I–] with k = 1.05 M–1 min–1. A reaction is carried out with the initial concentrations of both iodide and hydrogen peroxide equal to 0.300 M. What is the concentration of hydrogen peroxide after 5.00 min?
