rate of reaction

• The rate of reaction is the change in concentration with time.
• Average rate = total change/total time
• Rate = (change in conc)/(time taken)
• increasing temperature will increase the energy of the kinetic particles increasing collisions between reactions , which increase the rate of reaction
• factors that affect rate of reaction: temperature, concentration, surface area, catalysts, and pressure (for gases).
• Concentration - more reactants means more collisions so faster rate of reaction
• Catalysts - lower activation energy so more frequent successful collisions so faster rate of reaction
• Surface Area - larger surface area means more collisions so faster rate of reaction
• Temperature: at higher temperatures, molecules have more energy, collide more frequently, and with higher energy, leading to more successful collisions.
• Pressure: higher pressure leads to more frequent collisions between gas molecules, increasing the chances of successful collisions.
