Yes, both are endothermic; however, the first one is between gases and the second one APPEARS to be (it isn't balanced with charge) a dissociated of a solid. Therefore, the first one will be much more sensitive to pressure changes than the second (if it is sensitive at all).

how can you increases the concentration of the product in each of these reactions by varying temperature and pressure (caused by volume change)

-I don't understand what is the difference
aren't thses both endothermic reactions

so what would I write differntly about them

Br2 + Cl2 <=> 2BrCl deltaH = 14.64kJ
BaSo4 <=> Ba +SO4 delatH = 24267.3kJ
