Which of the following judgments about the value of the rate order of the reaction is correct? I) If the rate order is zero; the doubling of the reactant concentration does not affect the initial reaction rate. II) If the first order; the doubling of the reactant concentration doubles the initial rate of the reaction. III) If the reaction is second-order; increasing the reactant concentration by 2 times increases the reaction rate by 4 times. IV) The plot of each reaction rate order should be linear, even the value of the slope is negative or positive.
