D The three substances involved in each reaction all have a simple molecular structure,​

Answer 1

Answer:

I think the right one is b

Answer 2

Answer:

option(b) it is reversible

if you not satisfied I can explain

see,

option1= both are not exothermic because

you can think. supposed first equetion is exothermic reaction and in option (b) the equetion process is opposite to first one.

not a chance both are excothermi.

(c) is already wrong

D ) it is also incorrect because they don't have same moleculer structure it is depend upon valency

thankyou
