How would I go about solving this problem? Can someone show me an equation that can be used?
The decomposition of dimethyl ether at 504°C is a first-order reaction with a half-life of 27 min.
(CH3)2O(g) CH4(g) + H2(g) + CO(g)
What will be the total gas pressure after 2.18 h? [Hint: (CH3)2O and its decomposition products are the only gases present in the reaction vessel.
I found the pressure at 2.18 h to be 23.54. I do not know where to go from there
