Witryna(A) At low concentration of substrate, there is a steep increase in the rate of reaction with increasing substrate concentration. The catalytic site of the enzyme is empty, waiting for substrate to bind, for much of the time, and the rate at which product can be formed is limited by the concentration of substrate which is available. lambada tanssi

WitrynaIf you have a reaction with rate = k[A] Increasing the temperature whilst keeping the concentrations the same will speed up the reaction (rate increases due to more successful collisions) but the values for the concentration are still the same, therefore k must have increased. Increase in temperature = increase in k WitrynaInterpret graphs which show how the rate of reaction is affected by temperature and by the concentration and surface area of reactants. Sequence of activities Demonstration and introduction. Add some marble chips to hydrochloric acid in a conical flask with a side arm and draw attention to the gas evolved.
