e particles are available to collide. Temperature: Higher temperatures increase molecular kinetic energy, leading to more frequent and energetic collisions. Surface Area: For reactions involving solids, larger surface areas (e.g., powdered solids) provide more cont
um toward products; removing products shifts it toward reactants. Temperature change: For exothermic reactions, increasing temperature shifts equilibrium toward reactants; for endothermic reactions, it shifts toward products. Pressure change: Increasing pressure favors the side with fewer
