For the decomposition of hydrogen iodide on a gold surface at 150 °C


2 HI(g)H2(g) + I2(g)

the average rate of disappearance of HI over the time period from t = 0 s to t =1744 s is found to be 1.20E-4 M s-1

The average rate of formation of I2 over the same time period is  M s-1.

Thank you for the opportunity to help you with your question!

The average rate of formation of I2 over the same time period is 6.00E-5 M s-1.

It's the half of the rate of disappearance of HI. 

Please let me know if you need any clarification. I'm always happy to answer your questions.

can you also do this one? 

For the decomposition of hydrogen peroxide in dilute sodium hydroxide at 20 °C

2 H2O2(aq)2 H2O(l) + O2(g)

the average rate of disappearance of H2O2 over the time period from t = 0min to t = 368min is found to be 5.24E-5 M min-1

The average rate of formation of O2 over the same time period is  M min-1.

It's (5.24E-5)/2 M min-1=2.62E-5 M min-1
