Question

The polarimeter readings in an experiment to measure the rate of inversion of cane sugar (1st order reaction) were as follows

Then match the following. (Use : $lo g 35 = 1.54, lo g 3 = 0.48, lo g 2 = 0.3$ )

List - I	List - II
(A) The half life of the reaction	(P) 120 min.
(B) The solution is optically inactive at	(Q) $7. 5^{\circ}$
(C) The equimolar mixture of the products	(R) 75.2 min.
(D) The angle at half time	(S) laevorotatory
