Homework Statement
CH3OCH3(g) ---> CH4(g) + H2(g) + CO(g)
The reaction is conducted at 777.15 K, at constant volume beginning with pure ether.
Code:
t(hours) 0 390 777 1195 3155 +inf
P (torr) 312 408 488 562 779 931
Determine the order of the reaction and approximate the rate constant.
Homework Equations
1) PV = nRT
The Attempt at a Solution
I know I need a number of moles. Pressure is related to moles as stated by equation 1.
Unless I assign an arbitrary value to V, I cannot calculate a value for n.
I have written this table:
Code:
A --------------> 3B
t=0 a 0
t a-x +3x
t=+inf 0 3a
I know I have to convert P(tot) in P(ether) using:
P(tot) = (nA + nB) RT/V and
P(ether) = nA RT/V
But erm...
major brainfreeze. (as is usually the case when trying to study after a big meal lol!)
Thanks in advance.
