My lab is of an iodine clock reaction. I am being asked to calculate the initial rates for experiments 1, 2, and 3 from delta [S2082-]/ delta time. I know how to use the initial rate method however I am confused on how to obtain the initial concentration of S2082- and initial concentration of I-. Here is the information I am given: Volumes (mL) of solutions Experiment 0.20 M NAI 0.20 M NaCl 0.010 M Na2S2O3 2% starch 0.20 M K2SO4 0.20 M K2S208 1 2.0 2.0 2.0 1.0 2.0 2.0 2 2.0 2.0 2.0 1.0 0 4.0 3 4.0 0 2.0 1.0 2.0 2.0 How do I set up my experimental data chart to do the initial rate method?? I need to figure out what to put in as the initial concentration for S2082- and I- and what to put in as the initial rate for each one.
A reaction mixture at 175 initially contains 522 torr of NO and 421 torr of O2. At equilibrium, the total pressure in the reaction mixture is 748 torr. Calculate Kp at this temperature.
a termolecular reaction is carried out involving only two reactants, A and B, where two molecules of A are involved for each molecule of B. When the concentration of A is 0.415 M
at conditions of 785.0 torr of pressure and 15.0 Celsius temperature, a gas occupies a volume of 45.5 Celsius what will be the volume of the same gas at 745.0 torr and 30.0 Celsius.
