Consider the fictional reaction: which is catalyzed by reagent C. The rate of this reaction was monitored by looking at the disappearance of B under several different experimental setups at 298 K. Experiment [A] (M) [B] (M) [C] (M) Rate of disappearance of B (M/s)
1 0.400 0.0500 0.0500 0.0063
2 0.300 0.0500 0.0500 0.004725
3 0.300 0.100 0.0500 0.004725
4 0.300 0.0500 0.100 0.00945
5 0.400 0.0500 0.200 0.0252
