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.

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.

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
