Photographers use a rule of thumb, that a 10°C rise in temperature cuts development time in half, to determine how to modify film development time as the temperature varies. (a) Calculate the activation energy for the chemistry of film developing, assuming that "normal" temperature is 22°C. kJ/mol (b) If a certain film takes 7.4 min to develop at 22°C, how long will it take at 27°C? min
