To estimate the standard enthalpy change
of reaction D using reactions A-C, we can manipulate the given reactions to match the products and reactants of reaction D.First, let's manipulate reaction A to obtain
as a product:
Next, let's manipulate reaction C to obtain
as a product:
Now, we can add the manipulated reactions A and C to obtain reaction D:
Therefore, the estimated standard enthalpy change
of reaction D is
.
