Question

Classify the actions based on how they could affect a reaction rate.

Answer 1

Add a catalyst
- would increase rate of reaction;
Because adding catalyst would lower activation energies.

Decrease the concentration of a reactant
- would decrease rate of reaction; because there would be less molecule

Decrease the surface area of a solid reactant
 - decrease rate of reaction; less collisions because more particles would become isolated

Increase the temperature
- Would increase reaction; Because it would accelerate the movement of the particles and make them colliding faster
