For the following reactions, at 30 oC, a researcher adds 0.453 M X2 and 0.550 M Y2. X2(g) + 3Y2(g) ⇌2XY3(g) The researcher determined there was 0.280 M XY3 at equilibrium. What is the KC for this reaction at 30 oC?

Which of the following is true about the advertising response function f(n)=a(1-e-bn)?

Which of the following statements is/are correct. At equilibrium the rate of the forward reaction is greater than the rate of the reverse reaction At equilibrium the concentration of reactants and products stay constant At equilibrium the forward and reverse reaction stop

Which of the following statements is/are correct about a reaction that has the rate law shown below Rate = k [A]3 [B] [C]-1 The overall order of the reaction is 2 The units of the rate constant are M-2 time-1 Doubling the concentration of A, B and C will increase the rate by a factor of 8 (8x).

Use the reaction below at 25oC with the given conditions to determine the direction and provide the proper rationale.                        K = 9.10  Species Concentration (M) MnI3 2.395 MnBr3 2.450 The reaction is already at equilibrium will shift right to reach equilibrium will shift left to reach equilibrium  and therefore the concentration of reactants will decrease and the concentration of products will increase. the concentration of reactants and products will remain unchanged. the concentration of reactants will increase and the concentration of products will decrease.

Determine the value of Kp at 225oC for the reaction and data given below.  0.9721 atm  = 1.592 atm

Use the information provided below to determine which of the following will NOT shift the reaction.  

Which of the following acids can be represented by the image of the solution shown below?

Use the information provided below to determine which of the following will NOT shift the reaction.      

The next four (4) questions use the Model Design Project Selection model with the same spreadsheet shown in each of the questions and based on the following problem. Model Design is an architectural design company faced with the choice among 3 projects with given costs, personnel requirements, and expected returns. The total budget is limited to $100,000 and 8 architects. The firm must decide which project(s) to select in order to maximize the expected NPV subject to the available resources.
