Whats the activation energy and concentration and time of Take 10mL of 0.2 mol/L KI, 4mL of 0.2% starch solution and 8mL of 0.01 mol/L Na2S2O3, solution respectively into a 250mL beaker and mix them thoroughly, and then add 20mL of 0.2 mol/L (NH4)2S2O8 and 10mL of 0.2 mol/L KNO3 to the beaker quickly, start the stopwatch at once. keep on stirring the mixture. When the solution turns blue suddenly, record the time. In the 35 degrees C?
