Question

question 10 (1 point)
if a chemical reaction at stp is carried out in four steps and similar reaction is carried out in one step by another method, the total enthalpy change in the former case will
be four times greater than that of the second method
be four times lesser than that of the second method
be two times greater than that of the second method
be the same as in the second method
depend upon external physical conditions

Explanation:

According to Hess's Law, the enthalpy change of a reaction depends only on the initial and final states of the reaction, not on the path taken. Whether the reaction is carried out in one step or multiple steps, if the initial reactants and final products are the same, the total enthalpy change will be the same.

Answer:

be the same as in the second method
