88 kcal of heat is produced by 4 moles of N₂
Step-by-step explanation:
Given:
N₂ + 3H₂ → 2NH₃ +22 kcal
According to the reaction given, 1 mole of N₂ reacts with 3 moles of H₂ to release 22kcal of heat
If 4 moles of N₂ is taken then the amount of heat formed will be = 4 X 22 kcal
= 88 kcal
Therefore, 88 kcal of heat is produced by 4 moles of N₂
