What is the formula to find the value of $$t_{1/2}$$ for a zero order reaction?

In the presence of an acid, the initial concentration of cane sugar was reduced from $$ 0.20 $$ to $$ 0.10 $$ molar in $$ 5 $$ hours and from $$0.2 $$ to $$ 0.05 $$ molar in $$10 $$ hours. The reaction is of:

The rate constant for the first-order growth of bacteria can be calculated using:

The formation of $$H_2O_2$$ in the upper atmosphere follows the mechanism: $$H_2O+O\rightarrow 2OH \rightarrow H_2O_2$$; $$\Delta H=72\ kJ mol^{-1}$$, $$E_a=77\ kJ$$ $$mol^{-1}$$. 

Match the List-I and List-II:

At room temperature, the reaction between $$NO$$ and $$O_2$$ to give $$NO_2$$ is fast while that of between $$CO$$ and $$O_2$$ is slow. It is because:

A certain reaction rate increases $$1000$$ folds in the presence of a cataylst at $$27^{\circ}C$$. The activation energy of the original pathway is $$98\ kJ/mol$$. What is the activation energy of the new pathway?

A first-order reaction is $$40$$% complete after $$8$$ min. How long will it take before it is $$90$$% complete? 

Which among the following is wrong for $$1^{st}$$ order reaction?

Which of the following are the correct representations of a zero order reaction, where A represents the reactant?
