A catalyst increases the rate of the reaction by

The Arrhenius equation is

When the initial concentration of the reactant is doubled, the half-life period of the reaction is also doubled. Hence the order of the reaction is

If $k_{1}k\_1$ and $k_{2}k\_2$ are the rate constants of the given reaction in the presence and absence of the catalyst, then

If the ratio of rate constants at two temperatures for the given reaction is 2.5, the ratio of corresponding half-life periods is

For a zero order reaction, if Co is the initial concentration, then the half life period will be

The order of nuclear disintegration reaction is

The unit of rate constant for zero order reaction is

When a graph of $lo{g}_{10}klog\_\{10\}\; k$ is plotted against 1 /T, the slope of the line is,

In the reaction, $2A_{(g)}\to B(g)2A\_\{(g)\}\; \backslash rightarrow\; B\{(g)\}$ , the initial pressure of A is 2.5 atm. After 10 minutes the pressure becomes 2.2 atm. Hence the pressure of A is
