📐 Four Factors Affecting Rate of Reaction

2x2 grid showing four factors: temperature (faster particles), concentration (more particles), surface area (small cubes vs large cube), and catalyst (lower activation energy)

Figure 1: How each factor affects particle collisions. Temperature and concentration increase collision frequency; catalyst lowers the activation energy barrier.
