Question

2 P + 5 Cl2=2 PCl3 +886.0 kJ

How much energy will be produced when 1.382 mol P reacts with excess
Cl2?

Answer 1

612.2kJ are produced

Step-by-step explanation:

Based on the reaction:

2P + 5Cl₂ → 2PCl₃ + 886.0kJ

When 2 moles of P react with an excess of chlorine 886.0kJ are produced (That is 886.0kJ / 2mol P).

To solve this question we must use the last statement as follows:

1.382mol P * (886.0kJ / 2mol P) =

612.2kJ are produced
