Calculate the initial rate for the formation of c at 25 ∘c, if [a]=0.50m and [b]=0.075m

The initial rate for the formation of C at 25°C, if [A]=0.50M and [B]=0.075M is 0.022 M/s

Calculate the initial rate for the formation of C at 25°C, if [A]=0.50M and [B]=0.075M. Express your answer to two significant figures and include the appropriate units. Consider the reaction

A+2B → C

whose rate at 25°C was measured using three different sets of initial concentrations as listed in the following table:

Trial                    [A]                    [B]                    Rate

                         (M)                   (M)                    (M/s)

1                       0.20                 0.030                1.4 x 10 - 3  

2                       0.20                 0.060                2.9 x 10      - 3

3                       0.40                 0.030                5.8 x 10       - 3

We will take a look on 1st and 3rd data.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
