(A) The rate of a reaction is defined as the change in concentration of reactants or products per unit time. For a zero-order reaction,the rate of reaction is independent of the concentration of the reactants,i.e.,$\text{Rate} = k[A]^0 = k$. In the given data,the rate of the reaction remains approximately constant $(2.8 \times 10^{-2} \ mole \ litre^{-1} \ sec^{-1})$ at all given time intervals $(0, 10, 20, 30 \ sec)$. Since the rate does not change with time,the reaction must be of zero order.

The rates of a certain reaction $(dc/dt)$ at different times are as follows:
Time $(sec)$ Rate $(mole \ litre^{-1} \ sec^{-1})$
$0$ $2.8 \times 10^{-2}$
$10$ $2.78 \times 10^{-2}$
$20$ $2.81 \times 10^{-2}$
$30$ $2.79 \times 10^{-2}$

The reaction is:
