Calculating the rate constant is straightforward because we know that the slope of the plot of ln[A] versus t for a first-order reaction is − k. We can calculate the slope using any two points that lie on the line in the plot of ln[N 2 O 5 ] versus t.Using the points for t = 0 and 3000 s, Thus k = 4.820 × 10 s.alculating the rate constant is straightforward because we know that the slope of the plot of ln[A] versus t for a first-order reaction is − k.

B The rate law for the reaction is therefore. Calculating the rate constant is straightforward because we know that the slope of the plot of ln[A] versus t for a first-order reaction is − k. We can calculate the slope using any two points that lie on the line in the plot of ln[N 2 O 5 ] versus t.Using the points for t = 0 and 3000 s, Thus k = 4.820 × 10 s.xperimental data for this reaction at 330°C are listed in Table 14.5 Concentration of NO ; they are provided as [NO 2 ], ln[NO 2 ], and 1/[NO 2 ] versus time to correspond to the integrated rate laws for zeroth-, first-, and second-order reactions, respectively.

The rate constant is the slope. So if you have the line equation, take two points on the line and use the equation (y2-y1/x2-x1), take the value of that and plug it into the line equation and solve for y. That is your rate constant. could be y=mx+c for the equation sorry if that doesn't help.Katiee.1  0 badges.2  Follow.o if you have the line equation, take two points on the line and use the equation (y2-y1/x2-x1), take the value of that and plug it into the line equation and solve for y.

To determine the rate of reaction, and from that the rate constant, you will use an expression which relates the reaction rate to the concentration and time changes: The initial concentration of I2 + I3- for run n is labeled Cn, shown as Cv in Figure 1.o determine the rate of reaction, and from that the rate constant, you will use an expression which relates the reaction rate to the concentration and time changes: The initial concentration of I2 + I3- for run n is labeled Cn, shown as Cv in Figure 1.
