131 CH3OH(g) + C0( 3 ) + 2 H (g) HP = +91 kJ/mol rxn The reaction represented above goes essentially to completion. The reaction takes place in a rigid insulated vessel that is initially at 600 K A sample of CH, OH is placed in the previously evacuated vessel with a pressure of P1 at 600 K. What is the final pressure in the vessel after the reaction is complete and contents of the vessel are returned to 600 K?
A. P1/9 B. P1/3 C. P1 D. 3P1
