Rate Reaction Initial Define Describe Significance Investigations Factors

The initial rate of reaction, measured at t=0, is the true rate because substrate concentration changes affect the rate throughout the experiment.

The initial rate of reaction is the instantaneous rate at the beginning of an experiment (t=0), crucial because substrate concentration changes over time, affecting the rate.

Front Define initial rate of reaction and describe its significance in investigations into factors affecting rate of enzyme-controlled reactions.
Back Initial rate of reaction - instantaneous rate at the start of the reaction
  • Gradient of tangent to curve at t=0
  • Important because concentration of substrate always changes as the experiment proceeds - rate constantly changes
  • Therefore the only true rate of reaction is the initial rate of reaction (only moment where the two variables investigated are the only ones influencing rate)
