Question
For the reaction A+B+CD+E, the initial reaction rate was measured for various initial concentrations of reactants. The following data were collected: Trial 1 2 3 4 [Α] (M) 0.30 0.30 0.60 0.60 B (M) 0.30 0.30 0.30 0.60 с IM (M) 0.30 0.90 0.30 0.30 Initial rate (M/s) 9.0x10-5 2.7x10-4 3.6x10 3.6x10+ What is the reaction order with respect to C? Express your answer as an integer. ▸ View Available Hint(s) 1 Submit Previous Answers ✓ Correct The rate tripled when [C] was tripled. This indicates an order of 1 with respect to C because 3 = 3¹. ▾ Part D What is the value of the rate constant for this reaction? When entering compound units, indicate multiplication of units explicitly using a multiplication dot (in the menu). For example, M¹s¹. Express your answer to two significant figures and include the appropriate units.

Expert Solution
Step 1

D ) To calculate the rate constant we first need rate law for given reaction. Then we can plug data from any trial to calculate rate constant. 

 

E.) Using rate law , calculated rate constant we can calculate rate at given concentration of A , B and C .
