When initial concentration of a reactant is doubled in a reaction, its half-life period is not affected. The order of the reaction is

The activation energy of a reaction can be determined from the slope of which of the following graphs?

A reaction is 50% complete in 2 hours and 75% complete in 4 hours. The order of reaction is

For a reaction between A and B the order with respect to A is 2 and the other with respect to B is 3. The concentrations of both A and B are doubled, the rate will increase by a factor of
