An important component to driving is being alert The brain is an essential part of developing a quick reaction time. Lab Report On The Reaction Time 785 Words | 4 Pages. All chemical reactions have an energy barrier to overcome before the reaction will proceed. In the reaction time lab we dropped a metre stick and measured how quickly we could stop the stick from falling. Have test subject press as soon as they see the green light. In this study we will see how a specific enzyme could vary based on the different types of factors that affect it. The average reaction time for humans is 0.25 seconds to a visual stimulus, 0.17 for an audio stimulus, and 0.15 seconds for a touch stimulus. The degree Fahrenheit is only 100/180 as large as degree Celsius. deviation was also calculated for both the visual and auditory stimuli. Reaction time is a measure of the quickness an organism responds to some sort of stimulus. Most of these reactions are essentially reversible, and the direction in which the reaction goes depends on the concentration of the reactants in relation to the concentration of the products.
