How to measure rates of reaction
Web12 feb. 2024 · The reaction rate can be determined by measuring how fast the concentration of A or B decreases, or by how fast the concentration of AB … WebThere are four main factors that affect the rate of reaction are: concentration. This is a measure of how crowded the particles are in a solution and the frequencies of collision. Surface area This is a measure of how much solid is exposed to reaction and therefore how many collisions take place. Temperature.
