Question 2 :
Why do most chemical reaction rates increase rapidly as the temperature rises
Question 4 :
The correct expression for the rate of reaction of elementary reaction, $A + B \rightarrow C$ is :
Question 6 :
For the reaction $N_{2}O_{5}(g)\rightarrow 2NO_{2}(g)+\frac{1}{2}O_{2}(g)$ the value of rate of disappearance of $N_{2}O_{5}$ is given as 6.25 $\times$ 10$^{-3}$ mol  L$^{-1}$ S$^{-1}$. The rate of formation of $NO_{2}$ and $O_{2}$ is given respectively as:
