record Set the Reactant concentration to 2.0 mol/L.Click enter. The temperature should be set at 200 °C. Click enter. Check that the Catalyst concentration is set to 0.00 mol/L and the Surface area Record the time in minutes and seconds that it took to reach the half-life of the reaction.

what was the time
????

I'm sorry, but without the specific reaction being performed, I am unable to provide the exact time it would take to reach the half-life of the reaction. Each reaction has its own unique kinetics and half-life values.
