Question

Use the following table to answer g and h

1. You collected the following data in lab for the endothermic chemical reaction CO(g) + Cl2(g) → COC12(9) Trial # [CO] (M) [Cl] (M) Temperature (°C) No 5.0 10.0 10.0 20.0 20.0 1.9 2.0 512.0 512.0 512.0 512.0 778.0 452.0 Catalyst Initial Rate (M/s) 0.40 1.60 No 3.20 No 6.40 No | 11.32 Yes ??? 1.5 2.7

Le- chatelier's principle : It states that if a chemical reaction at equilibrium is subjected to a change in temperature, pressure or concentration, the equilibrium shifts to that direction by which the effect of the change is minimised.
