rate calculation

The average rate of reaction is calculated by determining the difference in [O 2 ] concentration over different intervals of time and dividing the difference by D ..

Example 2: The gaseous phase decomposition of dinitrogen pentoxide (N 2 O 5 ) to nitrogen dioxide (NO 2 ) and oxygen (O 2 ) is given by, For the reaction the concentration of O 2 was monitored and the following data were obtained. Time/s 0 600 1200 1800 3000 4200 [O 2 ] M 0 0...

A manufacturing concern employing a large number of workers finds that over a period of time, the average absentee rate is 2 workers per shift of 100. Calculate the probability that exactly 2 workers will be absent in a shift. => 1 e 2 or 4 e 2 or 2 e 2 or 2 e 2..

Instantaneous Rate - Example: Dehalogenation of trimethyl methyl bromide (CH 3 ) 3 CBr is given by the reaction. The following data were obtained. time/h [(CH3)3 CBr] x 10 - 2 M Instantaneous Rate Ms-1 0 10.39 3.15 8.96 6.20 7.76 Rate at time = 6.5 hours = 0.39 M/hr 10..

The simple interest on a principal of $300 at an interest rate of 5% is $45. For how many years is the simple interest calculated? => 3 or 6 or 5 or 4..

This method is used for reactions where more than one reactant species are involved. Initial rates of the reaction are determined by varying the concentration of only one reactant while keeping the concentrations of other reactants constant. Initial rate of reaction corres..

Rating of Electrical Appliances - Generally electrical appliances such as an electric bulb, geyser, heater, etc. are rated with power and voltage. If a bulb is rated 100W - 250V, it means that when a bulb is lit on a 250V supply, it consumes 100 W of electric power. Th..
