In these types of problems, we find out the final reaction (whose ∆H° to be calculate) with the help of given intermediate reaction by applying operations(like- adding, substrate, multiply be any digit) to get final reaction. As we applied the operation in reactions,same will be applied to their ∆H°.
please explain the steps to get to the answer Find AH° for the reaction: 2 C,H,OH...
