A study of the decomposition reaction 3RS2 –> 3R + 6S yields the following initial rate data   [RS2](mol L-1) Rate (mol/(L·s))     0.150 0.0394     0.250 0.109     0.350 0.214     0.500 0.438                          What is the rate constant (k) for the reaction? (Hint: rate = k[RS2]n)

A reaction of A produces two products, C and D , according to:A (aq) 2C(aq) + D(aq) When A is placed in the flask, its concentration is 0.050 M. The equilibrium concentration of A is measured to be 0.040 M. What is the equilibrium constant for this reaction?Hint:K = [C]2[D][A], Construct the ICE table :
