Question

The following experimental data were obtained in a study of the reaction 2 HI(g) H2(g) + I2(g). Predict the concentration of HI that would give a rate of 1.0 x 1-^-5 M/2 at 650 K.

Experiment Temperature (K) Initial [HI] Initial Reaction Rate (M/2)

1 700 0.10 1.8 x 10^-5

2 700 0.30 1.6 x 10^-4

3 800 0.20 3.9 x 10^-3

4 650 ? 1.0 x 10^-5

The final concentration of O2 is _____ molar. The change in concentration of O2 is _____ molar. The final concentration of NO is _____ molar and NO2 is _____molar. (use 2 s.f. for all, expressed as decimals fractions) Fill in the blanks.
