Use the data below to calculate a value for the electron affinity of chlorine.Ĭl 2(g) → 2Cl(g) +244 ( ΔH ⦵ B.E. Use the data below to determine the standard enthalpy change for the formation of one mole of calcium fluoride in its standard state, from its constituent elements in their standard states, under standard conditions.į 2(g) → 2F(g) +158 ( ΔH ⦵ B.E. Q1. Methanol can be regarded as a carbon-neutral fuel because it can be synthesised from carbon dioxide and hydrogen. Calculate the standard enthalpy change for this reaction using the data given below.
