Math Problem Statement
Liquid methanol
CH3OH
can be used as an alternative fuel in pickup and SUV engines. An industrial method for preparing it uses the catalytic hydrogenation of carbon monoxide:
How much heat (in
kJ
) is released when
15.0L
of
CO
at
85°C
and
112kPa
reacts with
18.0L
of
H2
at
75°C
and
744torr
? Be sure your answer has the correct number of significant figures.
Note: Reference the Fundamental constants, Conversion factors for non-SI units, and Thermodynamic properties of pure substances tables for additional information.
