PartA A chemical reaction that absorbs heat from the surroundings is said to be and has a AH at constant pressure. endothermic, positive endothermic, negative exothermic, negative exothermic, positive exothermic, neutral Submit Request Answer Solution Part (A):- Any chemical reaction, which absorbs the heat from the surrounding or any other external sources is said to be endothermic reaction . So, the enthalpy change will be positive for the endothermic reactions because heat is going to add to the system. So, the correct option will be (1) endothermic, positive. .

Solution
Part (A):-
Any chemical reaction, which absorbs the heat from the surrounding or any other external
sources is said to be endothermic reaction . So, the enthalpy change will be positive for the
endothermic reactions because heat is going to add to the system. So, the correct option will
be (1) endothermic, positive.
