Problem: Compounds of boron and hydrogen are remarkable for their unusual bonding and also for their reactivity. With the more reactive halogens, for example, diborane (B2H6) forms trihalides even at low temperatures:B2H6 (g) + 6Cl2 (g) ⟶ 2BCl3 (g) + 6HCl (g)       ΔH = −755.4 kJWhat is ΔH per kilogram of diborane that reacts?

🤓 Based on our data, we think this question is relevant for Professor Mamiya's class at TXSTATE.

Enthalpy, ΔH, is an extensive property and state function that represents the total amount of heat within a chemical reaction or system


In the given chemical reaction, the enthalpy is -755.4 kJ per mol of the reaction.

1 mol of the reaction uses 1 mol of B2H(diborane)


Moles can be related to mass using molar mass.
