All of the above influence the rate

Vedclass · Answer

(D) According to collision theory,the rate of a chemical reaction depends on three main factors: $1$. The frequency of collisions between reactant molecules,which is influenced by temperature and concentration. $2$. The energy of the collisions,which must exceed the activation energy $(E_a)$. $3$. The orientation or geometry of the colliding molecules (steric factor). Since temperature affects the kinetic energy (and thus velocity) and collision frequency,and orientation is a fundamental requirement for effective collisions,all the factors listed in options $A$,$B$,and $C$ influence the reaction rate. Therefore,none of the options provided are independent of the rate.

Step	Rate constant and Activation energy
$Step \ 1$	$k_1, E_{a_1} = 180 \ kJ \ mol^{-1}$
$Step \ 2$	$k_2, E_{a_2} = 80 \ kJ \ mol^{-1}$
$Step \ 3$	$k_3, E_{a_3} = 50 \ kJ \ mol^{-1}$

Collision theory is used to explain how chemical species undergo a reaction. Using this theory and the kinetic molecular model,which of the following does $NOT$ influence the rate of a chemical reaction?

What is the slope of the straight line for the graph drawn between $\ln k$ and $\frac{1}{T}$,where $k$ is the rate constant of a reaction at temperature $T$?

The following figure shows a graph of $\log_{10}K$ vs $\frac{1}{T}$,where $K$ is the rate constant and $T$ is the temperature. The straight line $BC$ has a slope,$\tan \theta = -\frac{1}{2.303}$,and an intercept of $5$ on the $Y$-axis. Thus,$E_a$,the energy of activation,is ....... $cal$.

Activation energy is given by the formula
