The order of the reaction is Question 6 options: 1) The steps that the reactants are...
In order for a reaction to reach equilibrium, there must be reversible steps between the reactants and the products. A classical reversible reaction is the phosgene reaction. The proposed mechanism has three reversible steps: Derive the rate law for this reaction in the steady state approximation. When the rate law is obtained. Examine it under conditions of equilibrium (rate = 0). Observe the relationship between the rate constants and another obvious quantity.

None of the answers are correct. QUESTION 7 You are trying to determine the reaction rate for a reaction with several intermediate steps. The rate for the overall reaction...
QUESTION 1 Variable(s) that affect rate include: temperature concentration pressure of gasses All of the above a and b only 1 points QUESTION 2 The rate constant (k) for a reaction: has units of M/s. changes with temperature is different for different concentrations of reactants All of the above b and c 1 points QUESTION 3 If a reactant is 2nd order, doubling the concentration of the reactant will: double the rate of the reaction triple the rate...
For the reaction A+B+C→D+E, the initial reaction rate was measured for various initial concentrations of reactants. The following data were collected: Trial [A] (M) [B] (M) [C] (M) Initial rate (M/s) 1 0.40 0.40 0.40 1.2×10−4 2 0.40 0.40 1.20 3.6×10−4 3 0.80 0.40 0.40 4.8×10−4 4 0.80 0.80 0.40 4.8×10−4 Rate law equation The rate of a chemical reaction depends on the concentrations of the reactants. For the general reaction between A and B, aA+bB⇌cC+dD The dependence of the...

Which statement is false concerning elementary steps in a reaction mechanism? the rate law can be deduced from the stoichiometry of reactants for an elementary step the overall molecularity for an elementary step is the sum of the stoichiometric coefficients for all reactants in that step the rate law for an elementary step must be determined experimentally the rate law for the overall reaction is always the same as the rate law for the slowest elementary step both (c) and...
1) What are the units on the rate constant ( the reaction is a 2nd order in one of the reactants and 0 in the other one) ? 2) What is the difference between reaction orders of the reactants and the stoichiometric coefficients of the reaction ? Do they have the same value? 3) Suppose we have a reaction of decomposition does the water affect the reaction rate? Assume we are not sure if the water is a reactant or...
