When methanol is used to generate hydrogen, it reacts with the following reaction:
CH3OH => CO + 2 H2
The reaction is second order with regards to methanol (CH3OH) and it is observed that 100 g/L of carbon monoxide (CO) can be produced in one day in a batch reactor, if you start with 200 g/L of methanol. What is the rate constant of this reaction (don’t forget to include units)?
The change in internal energy for the combustion of 1.0 mol of octane at a pressure of 1.0 atm is -5084.3 kJ .
If the change in enthalpy is -5074.0 kJ , how much work is done during the combustion?
Express the work in kilojoules to three significant figures.
An engine absorbs 100 J and rejects 60 J in each cycle. (a) What is its efficiency?
(b) If each
cycle takes 0.5 s, find the power output of this engine in watts.
