[tex]7.408 \;X 10 ^ {-3} m^{-2} s^{-1}[/tex] is rate of a reaction when k = 0.2, [A] = 3 M, [B] = 3 M, m = 1, n = 2 .
The rate at which the concentration of reactant or product participating in a chemical reaction alters is called the rate of reaction.
Rate of reaction = [tex]\frac{change \;in \;concentration}{time}[/tex] = (mol/litre)/time.
m= 1 and n = 2
[tex]rate = K [A] [B]^2[/tex]
[tex]0.2 = K X 3 X 3 ^2[/tex]
K = [tex]\frac{0.2 }{27 }[/tex]
K = [tex]7.408 \;X 10 ^ {-3} m^{-2} s^{-1}[/tex]
Hence, [tex]7.408 \;X 10 ^ {-3} m^{-2} s^{-1}[/tex] is rate of a reaction when k = 0.2, [A] = 3 M, [B] = 3 M, m = 1, n = 2 .
