What is the value of the rate constant k?
k is the first-order rate constant, which has units of 1/s. The method of determining the order of a reaction is known as the method of initial rates.
How are the pOH and pH linked?
The pOH of a solution is the negative logarithm of the hydroxide-ion concentration. The pH of a solution can be related to the pOH. Consider a solution with a pH =4.0. A basic solution has a pOH less than 7, while an acidic solution has a pOH of greater than 7.
What is a second order reaction?
Second order reactions can be defined as chemical reactions wherein the sum of the exponents in the corresponding rate law of the chemical reaction is equal to two. The rate of such a reaction can be written either as r = k[A]2, or as r = k[A][B].
What is the slope of a second order reaction?
Second-Order Reactions Therefore, if the reaction is second order, a plot of 1/[C]t versus t will produce a straight line with a slope that corresponds to the rate constant, k, and a y-intercept that corresponds to the inverse of the initial concentration, 1/[C]0 (Figure 17.8.

How do you know if its a second order reaction?
Determine the reaction order and the rate constant. If a plot of reactant concentration versus time is not linear, but a plot of 1/reaction concentration versus time is linear, then the reaction is second order.
What is pseudo order reaction give examples?
A Solved Question for You Solution: b) r = k[C. In the reaction, C+ H2O → C6H12O6 + C6H12O6 , water is present in large excess. Hence, it will not appear in the rate law expression. Thus, it is an example of pseudo first order reaction.
