Question

2. Consider the reaction energy diagram below, assuming that both the reactions are reversible. List ALL the statements that are TRUE. Use the process of elimination to help you here. TS2 TS1 EA2 EA1 Energy a) Product Pl is formed faster b) Product P2 is formed faster c) Product thermodynamically stable d) Product thermodynamically stable e) Performing the reaction at low carefully controlled temperature will favor the formation of product P. SM P1 P1 is more is P2 P2 more Reaction coordinate Performing the reaction at low, carefully controlled temperature will favor the formation of product P2 g) Running the reaction at sufficiently high temperature for a very short time will produce only the product P1 h) Running the reaction at sufficiently high temperature for a very short time will produce only the product P2. i) Running the reaction at sufficiently high temperature for a very long time will produce mostly the product P1 Running the reaction at sufficiently high temperature for a very long time will produce mostly the product P2 k) The reaction temperature has no effect on the ratio of products Pl to P2. m) When you intend to obtain product Pl selectively, the reaction temperature should be as low as possible, and the reaction time as short as practical n) When you intend to obtain product P2 selectively, the reaction temperature should be as low as possible, and the reaction time as short as practical o) The difference in the thermodynamic stabilities of products P1 and P2 determines the ability to produce selectively product P2 p) The difference in the thermodynamic stabilities of products P1 and P2 determines the ability to produce selectively product P1 q) The difference in the activation energies for reactions leading to products P1 and P2 determines the ability to produce selectively product Pl r) The difference in the activation energies for reactions leading to products P1 and P2 determines the ability to produce selectively product P2. A. b, e, f, h, i,k, n, p, r are true B. a,d, e,j,m,o, q are true C. a, d, e,h, j, m, o, q are true D.b, c, f, h,j,, n, o, r are true E. a, c, e, g, j, m, p, q are true

Answer 1

Let us first list down all the features of the products $P_{1}$ and $P_{2}$.-

$P_{1}$	$P_{2}$
Lower Energy required	Higher Energy required
less Stable	More Stable
Kinetically Controlled product	Thermodynamically Controlled product
Low temperature required	Forms only at high temperature
Formes faster	It takes much more time

hence, pointing to the above cases, Option B. i.e. a,d,e,j,m,o,q is correct.
