Solution

t = 1900 seconds is essentially the \"x-axis\"

so

finding \"y-axis\" will give us ln([SO2Cl2])

so...

the equation

y = -0.000290*t - 2.30

substitute t= 1900

y = -0.000290*1900 - 2.30 = - 2.851

note that

y = ln(C)

ln(C) = -2.851

C = exp(-2.851) = 0.05778 of SO2Cl2

the concentration is epxected to be about 0.05778 M of SO2Cl2

[SO2Cl2] = 0.05778 M
