Question 30 3 pts How would the reaction respond if some PtO is removed from the reaction mixture at equilibrium? CS2(g) + 2H2O(g) + Pt(s) = C(s) + 2H2S(g) + PtO(s) ΔΗχη = -55 kJ The reaction would make reactants to reach a new equilibrium. The equilibrium position of the reaction would not be affected. The reaction would make products to reach a new equilibrium, D Question 31 3 pts The temperature of the reaction below is increased and once...

In a chemical reaction, the reactant that limits the amount of product that can be formed is called the limiting reactant (or limiting reagent). The reaction will stop when all of the limiting reactant is consumed. In the sandwich example, bread was our limiting reactant. The reactant or reactants in a chemical reaction that remain when a reaction stops when the limiting reactant is completely consumed are called the excess reactant(s). The excess reactant(s) remain because there is nothing with...
