Homework Answers
According to collision theory-
In order to react ,the two ccolliding particles must follow the following two criteria:-
1. The molecules must collide with the proper orientation .
2. For a reaction to occur ,the atoms or molecules must collide with each other with enough activation energy.
So option (A) is correct option .
Add Answer to:
16. Molecules must collide with enough energy to overcome
the
a. activation energy barrier.
b. rate-determining...

INFORMATION reaction must also be perimental mea data are plotted in the sult means that the rate Because a reaction is faster at higher temperatures, the rate constant for the reaction m larger. The activation energy of a reaction can therefore be determined from experime surements of the rate constant at several temperatures. When the collected data are ple form In(k) vs T. as shown in Figure 2. a straight line is produced. This result means constant varies exponentially with...

A living cell extracts energy from organic "fuel" molecules in small, enzyme-catalyzed steps. This allows the process of energy extraction to be regulated. but less free energy is released from the molecules than would be released by burning them O and all of the energy is released as heat that can be used to do work in the cell O and some of the energy is stored in bonds of activated carriers O and more free energy is released from...
