Solution 2.2:
The stoichiometry of the dehydration reaction is
2CH30H ++ H20 + CH30CH3
The standard enthalpy change for this reaction at 298 K can be calculated using standard
heat of formation data from the literature and the following equation
MI =
(1)
Solution 3.5:
A. The rate expression is of the form
r = k(HMA) (V V ) (H + )
In logarithmic form, equation 1 becomes
(1)
log r = log k + log(HMA) + log(V V ) + log(H + )
(2)
The individual orders of the reaction can be determined by regression of data for
