Sorry I really don’t know I was trying to help and get points it might be D
Both have a continuous light spectra the fluorescent source makes a spectra with more intense bands of mercury

Answer:
Change in enthalpy for the reaction is -536 kJ
Explanation:
- Overall chemical reaction can be represented a summation of two given elementary steps with slight modification.
- Take reaction (1a) and divide stoichiometric coefficients by 2
- Take reverse reaction (2a) and divide stoichiometric coefficient by 2
- Then add these two modified elementary steps to get overall chemical reaction
- is an additive property. hence value of will be changed in accordance with modification
