Chemistry - Chemical Equilibrium Question with Solution | TestHub
For the given endothermic reaction : , the variation in concentration due to different changes is plotted. In List-II, various changes are given and you are supposed to match the entries in List-I With possible changes the system have undergone. Neglect the slope of change in concentrations when system approaches equilibrium
Options:
Answer:
Solution:
Effect I: Concentration just after the change is same, this means volume is constant, but then reaction moves backwards, this is possible only when B is added.
Effect II: concentration does not change, possible only when inert gas is added at constant volume.
Effect III: concentration of both A and B decreases just after change, it means inert gas is added at constant pressure since after that reaction goes forward(towards more number of moles).
Also, this change can be done by decreasing pressure at constant volume also, since to increase pressure reaction must move forward.
Effect IV: since reaction is endothermic, decrease in temperature move reaction backwards
