Initial concentration and conductivity change
Initial concentration and conductivity change
The concentration of ethyl acetate at the beginning of the reaction directly influences how much the conductivity changes as the reaction progresses. Higher initial concentration leads to larger conductivity changes.
Calculating the rate constant
Calculating the rate constant
The rate constant (k) can be calculated by measuring the change in conductivity over time, using the integrated rate law for a first-order reaction. This allows us to quantify how fast the reaction proceeds.
Temperature's role in hydrolysis
Temperature's role in hydrolysis
