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.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
