Increasing Temp Optimum Increases Rate Particles Explain Reaction

Increasing temperature towards the optimum boosts kinetic energy, increasing collision frequency and reaction rate.

Increasing temperature from below the optimum increases the kinetic energy of particles, leading to more frequent collisions and thus a higher rate of reaction.

Front Explain why increasing temp from below the optimum towards the optimum increases the rate of reaction.
Back Increasing temp from below optimum:
  • Increasing temp increases kinetic energy of the particles
  • This causes the particles to move faster and collide more frequently
  • Results in more frequent successful collisions between substrate and enzyme --> increase in rate
