Cane sugar is gradualaly converted into dextrose and laevuloe by dilute acid. The rate of inversion is observed by measuring the polarisation angle, at various times, when the following results are obtained: {:("Time (min)",0,10,20,30,40,100,oo),("Angle",32.4,28.8,25.5,22.4,19.6,-6.1,-14.1):} Show that the reaction is of first order. Calculate the value of t, when the solution is optically inactive.
