The reaction results in the formation of a gas, indicating an increase in entropy, which gives a negative ΔS value. The enthalpy change cannot be determined without more information, but since the reaction is endothermic (heat must be added), it is likely that ΔH is positive. Therefore, the best choice is B, a positive ΔH and a negative ΔS.
