Question
Consider the reaction
B)
Time () 0 10.0 20.0 30.0 40.0 50.0 () 0 1.10×103 4.10×103 5.90×103 7.10×103 7.70×103 Reaction rate can be defined either as theincrease in the concentration of a product perunit time or as the decrease of the concentration of areactant per unit time. By definition, reaction rate is apositive quantity. In the reaction rm Xrightarrow 2Y, for example,rm Y is being produced twice asfast as rm X is consumed and thus rm rate~of~X= frac{_1}{^2}(rate~of~Y) Each rate can be expressed as the change inconcentration over the change in time, Deltat: rm frac{-Delta [X]}{Delta {it t}}=frac{1}{2}Biggl ( frac{Delta [Y]}{Delta {it t}} Biggr ) Consider the reaction rm 2H_3PO_4 rightarrow P_2O_5+3H_2O Using the information in the following table, calculate theaverage rate of formation of rm P_2O_5 between 10.0 and 40.0rm s. Time (rm s) 0 10.0 20.0 30.0 40.0 50.0 rm [P_2O_5] (M) 0 1.1010?3 4.1010?3 5.9010?3 7.1010?3 7.7010?3 A)Determine the average rate of decomposition ofrm H_3PO_4 between 10.0 and 40.0rm s. (Anwser in Moles persecond) Rate of decomposition of rm H_3PO_4 = B) Consider the reaction rm 5Br^- {(aq)} + BrO_3^-{(aq)}+ 6H^+{(aq)} rightarrow 3Br_2{(aq)} + 3 H_2O{(l)} The average rate of consumption of rm Br^- is1.3510?4 {it M}/s over the first twominutes. What is the average rate of formation of rm Br_2 during the same timeinterval? Express your answer numerically inmolar per second. Rate of formation of rm Br_2 = Thanks! WIll rate high!
