Question

Consider the following reactions:

A -> 2B; deltaH = x kJ
B -> 2C; deltaH = y kJ
What would be the enthalpy change association with the reaction below? A -> 2C

Answer 1

The enthalpy change (ΔH) for the reaction A → 2C can be determined using Hess's law. To find the enthalpy change for the desired reaction, we can add the enthalpy changes for the individual reactions A → 2B and B → 2C.

Step-by-step explanation:

The enthalpy change (ΔH) for the reaction A → 2C can be determined using Hess's law. From the given information, we have the enthalpy changes (ΔH) for the reactions A → 2B and B → 2C. To find the enthalpy change for the desired reaction, we can add the enthalpy changes for the individual reactions. Therefore, ΔH(A → 2C) = ΔH(A → 2B) + ΔH(B → 2C).
