Answer: OA is a balanced equation.
Explanation: For an equation to be balanced, the number of atoms and the total charge of each element in the reaction, of the product and reactant side must be the same.
Considering OA; 6 atoms of nitrogen is present in the reactant side. Shifting to the product side, 6 atoms of nitrogen is also present. Taking the other element in the reaction into account, the number of atoms of each element balances on both sides.
A catalyst "provides an alternate reaction pathway with a lower activation energy". (2) is the correct answer.
Activation energy is the energy needed to conduct a chemical reaction. When a catalyst is put into the system, it makes the system require less activation energy, making the reaction go faster.
