92.0 torr/min.

Explanation:

For the reaction: 2NO (g) + Cl₂ (g) → 2NOCl (g).

∵ The rate of the reaction = - 1/2 (ΔP) NO/Δt = - (ΔP) Cl₂/Δt = 1/2 (ΔP) NOCl/Δt.

∵ (ΔP) NO/Δt = - 184 torr/min.

∴ The rate of change of the total pressure in the vessel = - 1/2 (ΔP) NO/Δt = ( - 1/2) ( - 184 torr/min) = 92.0 torr/min.
