WebFeb 12, 2024 · If an increase in reactant increases the half life, the reaction has zero-order kinetics. If it has no effect, it has first-order kinetics. If the increase in reactant decreases the half life, the reaction has second-order kinetics. References Chang, Raymond. Physical Chemistry for the Biosciences. 1st.
WebUnder this pseudo con- dition Eq. (1) becomes justified, and can form a basis for the derivation of a pseudo second order rate equation. In light of the above, the rate of removal of the solute from solution can be represented by pseudo second order rate kinetics as: − dC dt = k 2C 2 (3) 0 Here k 2 represents the ‘observed ’ rate ...
