In the reactions, A products with the concentration [A]0=1.512M,[A]is found to be 1.496at t=30S. With the initial concentration [A]0=2.584M,[A]is found to be 2.552M at t=1minute. What's the order of

Zero order

Explanation:

Reaction rate for experiment 1 =

1.496 - 1.512 / 30 - 0 = - 5.3 * 10^-4 Ms-1

Reaction rate for experiment 2

2.552 - 2.584/60 - 0 =  - 5.3 * 10^-4 Ms-1

So,

Since the rate of reaction does not change with change in concentration of reactants (identified by the fact that the rates of reaction 1 and reaction 2 are the same), the reaction is zero order.

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a
