WebDelta h in chemistry, also written as ∆H, refers to the change of enthalpy in a thermodynamic system caused by either absorption or emission of thermal energy. In simpler words, we may elaborate delta h as the total change in the system’s heat before and after a chemical reaction. Delta is symbolically represented by ∆and refers to “change”. WebMar 14, 2024 · According to the balanced equation, the reaction converts two moles of gaseous NO 2 into one mole of gaseous N 2 O 4, so we can now calculate ( ΔH): ΔH = -54.72 kJ + (8.314 J/mol·K) (298 K) (1 mol – 2 mol) ΔH = -54.72 kJ + (-2478 J) ΔH = -54.72 kJ + (-2.478 kJ) ΔH = -57.20 kJ This value of ΔH is a combination of two physical effects.
