The limiting reactant is not a property of the chemical equation. It depends entirely upon how much you have of a given substance when doing a reaction. Finding the Limiting Reactant When Given Mass of Reactants Now that you know how to find the limiting reactant, take a look at this ...
To react with all of the chlorine you would need 0.3 mol of aluminum, and there are 0.93 moles of aluminum. This confirms that there is enough aluminum to react with all of the chlorine. Chlorine is the limiting reactant, and aluminum is the excess reactant. References Chemistry LibreTexts:...
