A student made measurements on some electrochemical cells and calculated three quantities: The standard reaction free energy AG The equilibrium constant K at 25.0 °C. The cell potential under standard conditions E His results are listed below. Unfortunately, the student may have made some mistakes. Examine his results carefully and tick the box next to the incorrect quantity in each row, if any. Note: If there is a mistake in a row, only one of the three quantities listed is wrong. Also, you may assume the number of significarit digits in each quantity is correct.
