Chemistry · CHEMICAL BONDING AND MOLECULAR STRUCTURE

If the energy required to dissociate one mole of \( \text{H}_2 \) gas into atoms is \( 435.8\text{ kJ mol}^{-1} \), calculate the bond dissociation energy per single \( \text{H}-\text{H} \) bond in Joules. (Take \( N_A = 6.022 \times 10^{23}\text{ mol}^{-1} \))

1. A
   \( 1.45 \times 10^{-18}\text{ J} \)
2. B
   \( 3.62 \times 10^{-19}\text{ J} \)
3. C
   \( 7.24 \times 10^{-19}\text{ J} \)
4. D
   \( 4.35 \times 10^{-22}\text{ J} \)
