Hey there, I am doing IB and doing my extended essay on the effeciency of biodiesel compared to petrodiesel but I have no idea how I can work out the effeciency... I thought of simply working out how exothermic both react within a car engine but how do I do this in a laboratory? please give me some help
As it shall not overlap with other subjects, I will only look at the price and how exothermic the reaction is and then simply compare what you pay/ what you get
