Question 13: The decomposition of hydrogen peroxide: H202 -> H2 + 02 is a first order reaction with k=0.0438/min. If the initial concentration of H202 is 2.50 M and the decomposition is carried out, answer the following questions to three significant figures by filling in the blanks. The slope of a plot of In[H202] vs. t in minutes would be The time required until the concentration of H202 was 1.00 M: minutes The time required until the concentration of H2 was 1.00 M: minutes The H202 concentration after 10.0 minutes of decomposition: M The instantaneous rate of loss of H202 at 10.0 minutes (Hint: use the previous answer and remember the form of the first order rate law): M/min
