The unit of rate constant for zero order reaction is:

Which graph shows zero activation energy for reaction?

For a zero-order reaction with a rate constant k, the slope of the plot of reactant concentration against time is:

The relationship between rate constant and half-life period of zero-order reaction is given by:

The order of reaction for which half-life period is independent of initial concentration is:

The half-life of $^{14}C$ is 5570 yr. How many years will it take 90% of a sample to decompose?

Collision theory is applicable to 

$3A\longrightarrow B+C$

A certain radioactive isotope decay has $\alpha$-emission,
$_{ { Z }_{ 1 } }^{ { A }_{ 1 } }{ X }\longrightarrow$ $_{ { Z }_{ 1 }-2 }^{ { A }_{ 1 }-4 }{ Y }$
half life of $X$ is $10$ days. If $1$ $mol$ of $X$ is taken initially in a sealed container, then what volume of helium will be collected at STP after $20$ days?

One gram of $^{ 226 }{ Ra }$ has an activity of nearly $1 Ci$. The half life of $^{ 226 }{ Ra }$ is
