First-Order Reactions Relating concentration to time • In a first order reaction of the type A products • Rate= -Δ[A]/Δt • From the rate law we also know rate=k[A] • Combining the two equations we get • Using Calculus we can show for the above equation ...
The general rate of reaction formula for a rate law is Rate=k[A]x[B]y, where: k = rate constant (in s-1) [A] = concentration of reactant A x = order of reaction with respect to A [B] = concentration of reactant B y = order of reaction with respect to B First-order ...
There is a specific example cited in our NCERT Class 12 textbook, to find out the rate law equation for a general gaseous reaction, A⟶B+CA⟶B+CIt describes the entire procedure as shown:Let us consider a typical first order gas phase reaction A(g)⟶B(g)+C(g)A(g)⟶B(g)...
The integrated rate law ln [A] = –kt + ln [A]o(4-1) has the form of an equation for a straight line y = mx + b in which the slope m corresponds to the rate constant k. This means that, for a first-order reaction, a plot of ln [A] as a function of time gives a stra...
