Which of the following describes the correct order of energy conversions necessary to form electricity from bioenergy? O Chemical → Kinetic – Heat → Electric O Chemical → Heat → Kinetic Electric O Solar → Heat → Chemical → Kinetic → Electric Solar → Chemical → Heat → Kinetic → Electric
In which of the following conditions is the Gibbs free energy negative? O reaction is at equilibrium process is spontaneous O reaction is exothermic O process is not spontaneous
This question is only semi-random, it does relate to something said in the video. You must supply energy to start combustion reactions: you must drag a match across a rough surface to get it to light, the heat from a lit match or lighter is required to start charcoal burning, gas stoves often use an electric spark to ignite the methane (natural gas), etc. The fact that you must supply energy to get these reactions started is evidence of activation energy specific heat exoothermic reaction
