Question 1 if the enthalpy of a system increases, what value of δh describes the process? δh is positive. δh is negative. δh is zero δh increases.

The correct answer is is positive.

Explanation:

Enthalpy change is defined as the difference in enthalpies of all the product and the reactants each multiplied with their respective number of moles. It is represented as

The equation used to calculate enthalpy change is of a reaction is:  

As, the enthalpy of the system increases, it will lead to the formation of more products and thus making the enthalpy change of the reaction positive.

Hence, the correct answer is is positive.
