For the following process, H2 (g) → 2 H(g), it absorbs 436 kJ mol-1. Thus,

  • a)
    internal energy of the system is 436 kJ mol-1

  • b)
    change in internal energy is 436 kJ mol-1

  • c)
    internal energy of the system is 218 kJ mol-1

  • d)
    change in internal energy of the system is 218 kJ mol-1

Correct answer is option 'B'. Can you explain this answer?

For the following process, H2 (g) → 2 H(g), it absorbs 436 kJ mol...
In this process, one molecule of hydrogen gas dissociated into two gaseous atoms i.e. the number of gaseous particles increase leading to  a more disordered state. 
.Breaking of bond requires energy
It is not mentioned that the process is isobaric. If we assume that process is isobaric because volume can not remain constant as number of gaseous particles are increased, then change in internal energy = 436 kJ mol-1. The data of absorption gives us the value of q.

For the following process, H2 (g) → 2 H(g), it absorbs 436 kJ mol...
In order to determine the balanced chemical equation for the given process, we need more information about the reaction. The information provided, "H2 (g)", is the chemical formula for hydrogen gas. However, we need to know the other reactants or products involved in the process to write a complete balanced chemical equation.
