Question

In the conversion of compound X into compound Z, it was found that the reaction proceeded by way of Y, which could be isolated.
The following steps were involved.
X → Y; endothermic process
Y → Z; exothermic process
Which is the reaction profile of this conversion from X to Z?

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

From the given diagram we can see that except for option d, all the captions a,b,c follow the condition that X → Y; endothermic process, Y → Z; exothermic process but where as mentioned in the question that y can be isolated which means that y can be removed from the graph, so option a is the correct choice.
