For a chemical reaction to occur, all of the following must happen except:

Consider figure and mark the correct option.

For reaction $$A \rightarrow B$$, the rate law expression is $$-\dfrac{d[A]}{dT}=k[A]^{1/2}$$. If initial concentration of $$[A]$$ is $$[A]_0$$ then, which of the following statement is incorrect?

Rate of formation of $${ SO }_{ 3 }$$ according to the reaction $$2{ SO }_{ 2 }+O_{ 2 }\rightarrow 2{ SO }_{ 3 }\quad is\quad 1.6\times { 10 }^{ -3 }kg\quad min^{ -1 }$$. Hence rate at which $$SO_{ 2 }$$ reacts is:

What is the activation energy for this change?

Which of the following reaction has zero activation energy?

The activation energy of a reaction is $$58.3\ kJ/mole$$. The ratio of the rate constants at $$305K$$ and $$300K$$ is about:

A reaction takes place in three steps with the rate constant $$k_1, k_2$$ and $$k_3$$. The overall rate constant $$k=\dfrac{k_1(k_2)^{1/2}}{k_3}$$. If activation energies are $$40, 30$$ and $$20\ kJ$$ for step $$I, II$$ and $$III$$ respectively, the overall activation energy of reaction will be:

Which of the following reactants can be used to distinguish between benzaldehyde and Benzyl alcohol?

It is often stated that, near room temperature, a reaction rate doubles if the temperature increases by $${ 10 }^{ \circ  }C$$ Calculate the activation energy of a reaction that obeys this rule exactly.
