1.a plot of gibbs energy vid extent of reaction has
a)a minimum at equilibirium
b) a max at equilibirium
c) + slope at eq
d) - slope at eq
2. if half life of a reactant decreases wen temp is changed from T1 to T2
a) it is exothermic
B) it is endothermic
29Ans 1 shud be minimum at equilibrium
Ans 2..if T1 > T2 then the reaction shud be endothermic...as in endothermic reaction on increasing the temperature equilibrium shifts in forward direction so reactants are consumed faster so half life decreases..
1yes but it is not mentioned in the question if t1 > or <t2.
3for 1 the positive or negative depends on the value of the equilibrium constant,i hope dat the two qns are multiple choices.
106govind pls explain 1.
for 2: It can be both endothermic or exothermic
@govind: Not given whether reaction is reversible or not ..So even if T2 > T1 then also it can be both endothermic and exothermic
@sankara: first one was single option, second one multi option
