The rate of a chemical reaction responds in a linear fashion to changes in the concentration of reactant A. What can be said about reactant A?
Reactant A is zero order.
Reactant A is second order.
Reactant A is first order.
Reactant A is constant.
Reactant A is catalyzed.
Homework Answers
Linear fashion means rate is proportional to [A]^1., So order of reaction is 1 with respect to A.

Most of the time, the rate of a reaction depends on the
concentration of the reactant. In the case of second-order
reactions, the rate is proportional to the square of the
concentration of the reactant.

to understand how second-order reactions are identified by the
nature of their plots. You can also observe the rate law for
different reactions.

Chemists and engineers must be able to predict the changes in chemical concentration in a reaction. A model used for many single-reactant processes is Rate of change of concentration _kCn where C is the chemical concentration and k is the rate constant. The order of the reaction is the value of the exponent n. Solution methods for differential equations (which are discussed in Chapter 9) can show that the solution for a first-order reaction (n = 1) is and the...

Q-4 (7.10). The concentration of a reactant in a first-order chemical reaction that proceeds at a rate k can be described as follows: In(C) = ln(Co) - kt, where C is the concentration of the reactant at time t, Co is the initial concentration and t is the elapsed time since the reaction started. Consider an initial concentration of Co = 0.3 mol/L. The experiment was repeated n times to give a geometric mean of the concentration at time t...

Learning Goal: To understand how to use integrated rate laws to solve for concentration. A car starts at mile marker 145 on a highway and drives at 55 mi/hr in the direction of decreasing marker numbers. What mile marker will the car reach after 2 hours? This problem can easily be solved by calculating how far the car travels and subtracting that distance from the starting marker of 145. 55 mi/hr×2 hr=110 miles traveled milemarker 145−110 miles=milemarker 35 If we...

(a) Sketch a general drawing that shows how reaction rate varies with initial concentration of reactant [A] for a second-order reaction. (b ) How does the rate of reaction changes when reactant [A] is doubled if the reaction is second- order with respect to A? © The reaction A?B has been experimentally determined to be second order. The initial rate is 0.0100 M/s at an initial concentration of A of 0.100 M. What is the initial rate at [A] =...
