How to work out the activation energy
WebIn order to calculate the activation energy we need an equation that relates the rate constant of a reaction with the temperature (energy) of the system. This equation is called the Arrhenius Equation: Where Z (or A in modern times) is a constant related to the geometry needed, k is the rate constant, R is the gas constant (8.314 J/mol-K), T is ... WebIn his famous book Thinking Fast and Slow, psychologist Daniel Kahneman outlines how our brains engage in two distinct processes when it comes to decision-making. System 1 thinking refers to our automatic behaviour, like recalling the answer to 2+2 or dialling a phone number you know by heart.
