For the reaction:  IO3-1 + 5I-1 + 6H+1 –> 3I2 + 3H2O. If d[H2O]/dt  = 3.0 x 10-3 M/sec.  What is the rate of disappearance of H+1 in M/sec?  

For the reaction below, the partial pressure of A is 0.0105 atm and the partial pressure of D is 34.2 atm. What is the value of Q for the reaction?  In which direction does the reaction need to shift to reach equilibrium? 2A (g) + B (s) ⇌ 2C (s) + D (g)     Kp = 8210   Value of Q = [q]  Shift to reach equilibrium = [shift]    

The following initial rates are obtained at a certain temperature for the reaction A + 2 B –> C + 2D Expt. A (M) B (B) Rate (M/s) 1 0.22 0.16 6.1 x 10-4 2 0.44 0.32 1.2 x 10-3 3 0.44 0.16 6.1 x 10-4   Determine the order of the reaction with respect to each reactant and write the rate law for the reaction.  What is the rate of the reaction when  the concentration of B = 0.24M? Rate Law = [ratelaw] Rate when B = 0.24M is [rate] Put numerical answers in exponential notation using e. Ex. 1.0e-5
