The rate of the reaction in terms of the "disappearance of reactant" includes the change in the concentration of the reactant, the time interval, and the coefficient of the reactant.

consider the following reaction:

2a+3b→3c+2d

the concentrations of reactant a at three different time intervals are given. use the following data to determine the average rate of reaction in terms of the disappearance of reactant a between time = 0 s and time = 20 s .

time (s ) 0 20 40
[a](m) 0.0400 0.0240 0.0180
express your answer in molar concentration per second to three significant figures.

part b

the rate of the reaction in terms of the "appearance of product" includes the change in the concentration of the product, the time interval, and the coefficient of the product.

consider the following reaction:

2a+3b→3c+2d

the concentrations of product c at three different time intervals are given. use the following data to determine the rate of reaction in terms of the appearance of product c between time = 0 s and time = 20 s .

time (s ) 0 20 40
[c](m) 0.000 0.0240 0.0480
express your answer in molar concentration per second to three significant figures.

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl+4h2o enter the elemental symbol. view available hint(s) is reduced
