Nitrosylsulfuric acid, HSO5N, can be formed by reacting HNO2 with H2SO4 under cold conditions. HNO2 (aq) + H2SO4 (aq) ? HSO5N (aq) + H2O (l) This is an exothermic reaction. Which of the following changes to a chemical system of the reaction above at equilibrium would cause it to shift right (i.e. promote the formation of more product)? Group of answer choices Increasing the external pressure Adding NaOH (a strong base) Removing some HNO2 Adding additional H2SO4 Increasing the temperature
