When methanol is used to generate hydrogen, it reacts with the following reaction:
CH3OH>>>>CO+2H2
The reaction is second order in methanol, and it is observed that 100g of carbon monoxide can be produced in one day in a batch reactor, if you start with 200g of methanol. What is the rate constant for this reaction?
When methanol is used to generate hydrogen, it reacts with the following reaction:
