Question 3

Nitrosyl chloride reaches dynamic equilibrium in a sealed vessel.

2NOCl(g)⇌2NO(g)+Cl2(g) \mathrm{2NOCl(g) \rightleftharpoons 2NO(g) + Cl_{2}(g)} 2NOCl(g)⇌2NO(g)+Cl2​(g)

During a 40 ms interval, 7.2 × 1018 molecules of nitrosyl chloride form in the reverse reaction.

Calculate the number of molecules of chlorine formed by the forward reaction every second.
