Chemistry-Rate Law Problem?

The rate of the reaction CO2(g) + H2(g) → H2O(g) + CO(g) was determined in three experiments at 650 K. The results are given in the following table: Experiment 1- [CO2] in mM=20.0, [H2] in mM=12.0, rate in mM/min= 2.3 Experiment 2- [CO2] in mM=20.0, [H2] in mM=24.0, rate in mM/min= 4.6 Experiment 3- [CO2] in... show more The rate of the reaction CO2(g) + H2(g) → H2O(g) + CO(g) was determined in three experiments at 650 K. The results are given in the following table:

Experiment 1- [CO2] in mM=20.0, [H2] in mM=12.0, rate in mM/min= 2.3

Experiment 2- [CO2] in mM=20.0, [H2] in mM=24.0, rate in mM/min= 4.6

Experiment 3- [CO2] in mM=40.0, [H2] in mM=12.0, rate in mM/min= 4.6


A) What is the rate law for this reaction?

B) What is the rate constant k?

C) What would be the rate if starting concentrations were [CO2]=40.0 mM and [H2]=24.0 mM
