FREE Expert Solution

Based on the given decomposition reaction of oxalate ion, we’re asked to determine which option would increase the rate of decomposition.

Reaction rates are influenced by 4 factors:

1. Concentration: for a reaction to occur, molecules must collide.

Increasing the number of molecules in a container increases their collisions and thereby causes the rate to increase.

2. Surface area: the greater the surface area, the greater the chance for the reaction to occur and the faster the reaction can occur.

The surface area depends on the geometry or structure of the compound.
