The decomposition of dimethyl ether at 504°C is a first order reaction with a half-life of 27.0 min.
(CH₃)₂O(g) → CH₄(g) + H₂(g) + CO(g)
A reaction vessel is charged with dimethyl ether at an initial pressure of 725 torr, and the reaction is initiated by rapidly heating the vessel to 504°C. Assuming a negligible time lag in beginning the reaction, what will the total gas pressure be in the vessel after 80.0 min? (assume ideal behavior)
