quickly please most likely rate law for the reaction shown below?25. If increasing the concentration of either reactant increases the overall rate of reaction, which is theA) Rate = k[CH3CH₂Br] [OH-]CH3CH₂Br(aq) + OH-(aq) → CH3CH₂OH(aq) + Br(aq)B) Rate = k[CH3CH₂Br][ OH-]0C) Rate = k[CH³CH₂Br][OH-]D) Rate = k[CH3CH₂OH] [Br]E) Rate = k[CH3CH₂OH][ Br]26. Why can the initial rate of reaction (the rate of the reaction during the time when the reaction firsttakes place) be used to determine the rate law of a reaction?A) At the beginning of the reaction, the reactants are at their highest concentration and monitoring the rateof the reaction when initial concentrations are changed provides information about how each reactantimpacts the rate.B) At the beginning of the reaction, the reaction is at its slowest point, and therefore this providesinformation about how the reactants are interacting with each other in the reaction.C) At the beginning of the reaction, the reactants behave as catalysts and can lower the activation energyof the reaction.27. Which of the following statements regarding catalysts is true?A) By lowering the activation energy of the reactants, catalysts can increase the rate of reaction.B) Catalysts can make a reaction more spontaneous by making the enthalpy more exothermic.C) Adding a catalyst to a reaction increases the concentration of the reactants.D) A and B are correctE) A, B, and C are correct28. The decomposition of hydrogen peroxide is shown below. If the first order time-integrated rateconstant for this reaction is 3.21 x 105 sec¹, how long will it take for half of the initial hydrogen peroxideto decompose?2H₂O2(1)→ 2H₂O(1) + O₂(g)A) 11.3 secondsB) 1.45 x 10² seconds.C) 3.21 x 10³ seconds.D) 2.16 x 104 seconds.29. If a reactant is observed to be zero order in a reaction, which of the following statements is true? (hint:write the rate law with a reactant having a 0 reaction order; what would this mean mathematically?)A) That reactant must be a spectator and does not participate in the net reaction.B) That reactant must decompose first prior to reacting with the other reactant.C) That reactant participates in the net reaction, but it does not participate in the rate determining step ofthe reaction.30. If the gauge pressure of a football is 12.5 psi, how many moles of air must be in the football (assumethe football volume is 4.60 L and the temperature of the ball = 25.0 °C; assume the atmospheric pressureis 1.00 atm; 1 atm = 14.7 psi)A) 0.348 moles B) 1.00 moles C) 2.88 moles D) 4.44 moles阿NamL
