Consider the general form of a predictive hypothesis:
$H_0: \text{There is no significant effect or relationship.}$ (Null Hypothesis)
$H_1: \text{There is a significant effect or relationship.}$ (Alternative Hypothesis)

For a specific example in chemical kinetics, hypothesizing the effect of a catalyst on reaction rate:
$H_0: \text{The addition of platinum catalyst does not alter the activation energy of the decomposition of hydrogen peroxide at 298.15 K and 101.325 kPa.}$
$H_1: \text{The addition of platinum catalyst decreases the activation energy of the decomposition of hydrogen peroxide at 298.15 K and 101.325 kPa.}$
