CH3COOC2H5(aq) + OH-(aq) ->CH3COO- + C2H5OH(aq)
Was measured at several temperatures and the following data was collected
k(M-1 s-1)...............temp(c).0521.......................15.101.........................25.184.........................35.332.........................45
Using this data, graph ln k 1/T. using your graph determine the value of Ea please show work and show a graph
