1) The following reaction is exothermic. Which change will shift the equilibrium to the left?

2SO2(g) +O2(G) 2SO3(g)

a- rising the temp b-decrease pressure c-increase volume d-all of the above e-none of the above

2)Which of the following is the strongest oxidizing agent?

a- ClO2(s), b-I- (aq), c- Li+ (aq), d- SO4 2- (aq), e- MnO4-(aq)

Solutions

Expert Solution

1) answer is D

explanation a) if the temp is increased since the reaction is exothermic it will try to absorb the heat in order to bring back equilibrium which will tend to endothermic leading equilibrium to shift towards left

b)since the no of moles is more in left so according to le Chateliers principal it will shift towards left

c)increasing the volume will decrease the concertration in left of the reacton leading to equilibrium towards left

2)answer is C

higher the oxydation state more they become electronegative in this case Mn is at +7 state so it the most electronegative leading to stronger oxydizing agent SO4 is in +6 so it less stronger than Mn
