If HCl concentration is reduced by 50% and the rate is reduced by 25% what is the reaction order? This is assuming the other reactant is at a constant concentration.
Use an Arrhenius plot to determine the activation barrier for the reaction. Express your answer using three significant figures. (units = kJ/mol)
When we go down a group, electron affinity should become more positive (less energy released), since the electron is added at increasing distances from the nucleus.
