Answer:
negative
Explanation:
Entropy is a measure of the "disorder" in a system.
In this reaction, the amount of disorder decreases. This is because one gas molecule (NH₃) has more order than two gas molecules (N₂ and H₂). Therefore, the entropy change should be negative.
On treatement of 2 -with hydrogen gas and lindlar catalyst, the major product obtained is cis-2butene.
Answer:
It is a neutral atom and does not carry a charge
