Question

Concentration data is commonly monitored during a reaction to determine the order with respect to a reactant. Consider the types of observations listed, and determine which order is likely for that reactant. Assume all other factors are held constant.

An increase in the concentration of the reactant in solution causes the reaction rate to increase exponentially.
Choose...first order, second order, zero order
The reaction rate increases in direct proportion to the concentration of the reactant in solution.
Choose...first order, second order, zero order
The reaction rate is constant regardless of the amount of reactant in solution.
Choose...first order, second order, zero order

Answer 1

An increase in the concentration of the reactant in solution causes the reaction rate to increase exponentially - first order

The reaction rate increases in direct proportion to the concentration of the reactant in solution -second order

The reaction rate is constant regardless of the amount of reactant in solution - zero order

Step-by-step explanation:

The Order of Reaction refers to the power dependence of the rate on the concentration of each reactant. The order of reaction is determined experimentally and not necessarily by inspection.

Typically, in a second order reaction, the rate of reaction increases in proportion to increase in concentration.

For a first order reaction, the rate of reaction increases exponentially as the increase in concentration.

For a zero order reaction, the rate of reaction is independent of the concentration of the reactant.
