Question

if a process
equires energy\...
it is endothermic and the δh value is positive.
it is endothermic and the δh value is negative.
it is exothermic and the δh value is positive.
it is exothermic and the δh value is negative.

Explanation:

• Endothermic processes absorb energy.
• In endothermic reactions, the enthalpy change ($\Delta H$) is positive because the system gains heat.
• Exothermic processes release energy, and $\Delta H$ is negative.

Answer:

It is endothermic and the $\Delta H$ value is positive.
