1 . Use table 6.1 in the textbook to estimate the H for the reaction below. Bo +HBr For each of the following cases, use the information given to determine whether or not the equilibrium will favor products over reactants: 2. a. A reaction with Keq = 1.2 b. A reaction with Keq = 0.2 C. A reaction with a positive G d. An exothermic reaction with a positive S e. An endothermic reaction with a negative AS 3. Identify the nucleophilic and electrophilic center of the compound below: Li

Solution

since table is not given in question 1, so i am solving second question,

2) if Keq > 1 it will favors products, and if Keq < 1 it will favor reactants.

* +ve delta G means reaction is non spontaneous, so it will favour reactants

* -ve delta G means reaction is spontaneous, and it favours products,

a) here keq > 1, so it will favour products over reactants.

b) here keq <1, so it will not favour products over reactants.

c) delta G is positive means, it will not favour product over reactants.

d) S = +ve exothermic means H = -ve,

So, according to equation,

G = H - TS,

G = - ve

Which means it will favour products over reactants

e)   S = - ve , endothermic reaction means H = +ve

G = H - TS,

G = +ve

Which means it will favour products over reactants.
