( I) Bonds are broken, and the reaction is endothermic. (2) Bonds are broken , and the reaction is exothermic. (3) Bonds are formed, and the reaction is endothermic. (4) Bonds are formed, and the reaction is exothermic.
Answer: Option (1) is the correct answer. ;
The reaction shows that nitrogen gas ( N 2 ) is broken down into nitrogen atoms ( N ), which requires energy input. This indicates that bonds are broken and the reaction is endothermic. The correct choice is A.
;
5. <25 M2: This represents any value less than 25, making it the smallest.4. 25-50 M2: This range falls entirely after the "<25 M2" category and before the next one.3. 50-99 M2: This range is larger than the previous one but still smaller than the next two.2. 100-200 M2: This range encompasses values between 100 and 200, placing it before the final option.1. >200 M2: This represents any value greater than 200, making it the largest.
