In a chemical reaction, what is the limiting reactant? Check all that apply. The reactant that makes the least amount of product. The reactant that determines the maximum amount of product that can be formed in a reaction. The reactant that makes the most amount of product. The reactant that runs out first.

1. If a reactant is added to a reaction at equilibrium, which way will the reaction shift to re-establish equilibrium (use forward or backward)? Why? 2. If a reaction is endothermic, is heat a reactant or a product? 3. For an endothermic reaction, if heat is added, which way will the reaction shift to re-establish equilibrium (use forward or backward)? Explain your reasoning. 4. A reaction has initial concentration of 0.330 M Fe3+ and 0.210 M SCN- At equilibrium, the...

The rate of the reaction in terms of the "disappearance of reactant" includes the change in the concentration of the reactant, the time interval, and the coefficient of the reactant. Consider the following reaction: 2A+3B→3C+2D The concentrations of reactant A at three different time intervals are given. Use the following data to determine the average rate of reaction in terms of the disappearance of reactant A between time = 0 s and time = 20 s . Time (s )...
