Question

General Chemistry 4th Edition University Science Books presented by Sapling Leaming t(s) IN2Os] (M) 1.82 The decomposition of N205 can be described by the equation 0 205 1.60 Given these data for the reaction at 45°C in carbon tetrachloride solution, calculate the average rate of reaction for each successive time interval 1.34 1.15 725 Interval:0s to 205 s 205 s to 486 s 486 s to 725 s Number Number Number Reaction rate: M/s M/ s M/s Previous Give Up & View Solution O Check Answer Next Exit Hint

Explanation / Answer

Reaction rate --> (Cfinal - Cinitial ) /(Tfinal - tinitial)

Rate 1 = (1.60-1.82)/(205-0) = -0.001073 M/s

Rate 2 = (1.34-1.60)/(486-205) = -0.000925 M/s

Rate 3 = (1.15-1.34)/(725-486) = -0.0007949 M/s
