Do reactants that collide always react together?
0.0784 moles of substance A is dissolved in water to make a 2.00 L solution. Then, substance B is added, without changing the volume of the solution, and the following reaction takes place: 2A (aq) + 3B (aq) →2C (aq) During the course of the reaction, concentration of A is monitored. After 100 seconds into the reaction, it was found that 0.0570 moles of A is remaining. Calculate the rate of disappearance of A in the first 100 seconds of the reaction. Hint: Since rate is defined as the change in molar concentration (mol/L) over time, start by calculating molarity of A in the beginning of the reaction, and 100 seconds after. rate = A [A] At O 3.92x104 M.s1 O 2.14x104 MS1 O 1.07x10 M.s1 O 5.34x10 Ms
