Question

Suppose heats of reaction at 25°C are measured experimentally for the following set of reactions: 2 A + B ? 2C: ??°_{r1} = -1000 kJ/mol A + D ? C + 3 E: ??°_{r2} = -2000 kJ/mol Use Hess's law to show that for B + 6 E ? 2 D: ??°_r = +3000 kJ/mol

Step 1

Step 1: Write down the given reactions with their respective enthalpy changes: \[ \text{Reaction 1: } 2A + B \rightarrow 2C, \quad \Delta H_1^\circ = -1000 \text{ kJ/mol} \] \[ \text{Reaction 2: } A + D \rightarrow C + 3E, \quad \Delta H_2^\circ = -2000 \text{ Show more…

Suppose heats of reaction at 25°C are measured experimentally for the following set of reactions: 2A + B → 2C: ΔĤ°_r1 = -1000 kJ/mol A + D → C + 3E: ΔĤ°_r2 = -2000 kJ/mol Use Hess's law to show that for B + 6E → 2D: ΔĤ°_r = +3000 kJ/mol
