Explanation / Answer

16)
Increasing Temperature will shift the reaction in a direction which absorbs heat as per Le chatelier Principle
Forward reaction is endothermic in nature
hence, forward reaction will be favoured
So, Equilibrium moves to product side and Kc will increase

Answer: C

17)
K = [BrCl]^2 / [Br2][Cl2]
= (2.27*10^-3)^2 / (0.384*0.446)
= 3.01*10^-5
Answer: D
