3. The rate laws that we looked at in this course all had integers as exponents. For instance, we looked at first-order and second-order rate laws of the form rate = k[A]1 and rate = k[A]2. Your textbook also pointed out rate laws of higher order, such as rate = k[A][B]2, which is first-order in A, second-order in B, and third-order overall. But the exponents in rate laws aren’t always integers, and they aren’t even always positive. In biochemistry, for...
The table below shows values for initial rates as a function of the concentrations of three reactants A, B and C. Which of the rate laws is most consistent with the data? Show your calculations, or explain your reasoning. Determine the value of k. These are the possible rate laws. The data is consistent with one of them. Rate = k[A]1[B]1.5[C]-1 Rate = k[A]1.5[B]1.0[C]-1 Rate = k[A]1[B]0.5[C]-1 Rate = k[A]0.5[B]1.5[C]-1 Rate = k[A]0.5[B]1.5[C]1 Rate = k[A]1.5[B]0.5[C]1 This...
You make a one-off initial investment of $3,000 in a bank account that pays 3% interest oer year, with interest compounded 2 times per year. How long will it take for the value of the investment to double Consider the reaction, aA+bB-CdD+E where C is a catalyst. A generic rate equation for this reaction is: rate = k[A]”[B] [CS Which of the statements below about this generic rate equation is false? Select one: a. The exponents q, r, and s...
Helpful Stuff Gas Arrhenius Equation: k = Ae-Ea/RT Constant: R= 8.314 J/mol K Integrated Rate Laws and Half-Lives: Zero order: [A] = -kt + [A]. t1/2 =[A]/2k • First order: In[A] = -kt + In[A]. t1/2 = 0.693/k • Second order: 1/[A] = kt + 1/[A] t1/2 = 1/k[A] • Pseudo first order: Use first order integrated rate law for the pseudo-first order reactant; other reactant concentrations remain constant, but are still present in overall rate law 1. You study...
