The rate equation for the hydrolysis of sucrose to fructose and glucose C₁2H₂O(aq) + H₂O()→ CsH₁2Os(aq) + CH₂Os (aq) is-A[sucrose]/At=k[C₁₂H₂O₂). After 28 minutes at 27 °C, the sucrose concentration decreased from 0.0112 M to 0.0090 M. Find the rate constant k. k= min-1 Submit Answer Try Another Version 4 item attempts remaining

A student collected conducted 6 kinetics experiments for one reaction by holding the concentrations of ALL the reactants and catalyst constant and varying the temperature. After determining the rate constant for this reaction at the 6 different temperatures, an Arrhenius Plot was made. The graph resulted in a straight line. The equation for the straight line was: y= -4,257.15 x + 14.326 What is the Activation Energy (in Joules/mol) for this reaction at 30 oC? Do not include the units in your answer.
