For this problem why is SO2 the limiting reactant if there are equal amounts of reactants and SO2 has a greater coefficient, why would it be the limiting reactant?

SO2 would be the limiting reactant because if you had 0.030 mol of O2, then by the molar ratio given to us by the coefficients of the reaction (2 mol SO2 for every 1 mol of O2), then you'd need 0.060 mol of SO2 to fully react. However, in the question, we are given only 0.030 mol of SO2, half the number of moles that would be needed to fully react with 0.030 mol of O2. Because of this, SO2 is the limiting reaction
