  3. begin mathsize 14px style negative sign 125 space kJ space mol to the power of negative sign 1 end exponent end style 

  4. begin mathsize 14px style plus 125 space kJ space mol to the power of negative sign 1 end exponent end style 

  5. begin mathsize 14px style plus 135 space kJ space mol to the power of negative sign 1 end exponent end style 

Jawaban:

Energi ikatan reaktan:

begin mathsize 14px style 1 cross times C bond H equals 412 space kJ 1 cross times C triple bond N equals 890 space kJ 2 cross times H bond H equals 2 cross times 436 space kJ equals 872 space kJ end style

Energi ikatan produk:

begin mathsize 14px style 3 cross times C bond H space equals 3 cross times 412 equals 1.236 space kJ space 1 cross times C bond N space equals 293 space kJ space 2 cross times N bond H space equals 2 cross times 390 equals 780 space kJ end style

Error converting from MathML to accessible text.

Jadi, jawaban yang benar adalahundefinedB.
