Which of the following is a strong acid

HCI (Hydrochloric acid)

What does the rate law use to determine the rate of a reaction

The rate of a reaction is calculated using the concentrations of reactants.

What must be known for the rate constant to be calculated from the rate law

The reaction rate at known reactant concentrations.

What causes pressure changes of reactants to affect the reaction rate

The frequency of collisions is changed.

How does increasing the temperature affect collisions

It increases the number of high-energy collisions

Which of the following acts as a catalyst in catalytic converters

Metal

What happens to the potential energy of the molecules in a reaction

The potential energy of the molecules change during a reaction.

What information does the rate constant give from the rate law

It tells how much the reaction rate is affected by concentrations.

What is true of a Brnsted Lowry base

Bornsted Lowry base is an acid base reaction theory. The ideal came from Johannes Nicolaus Bronsted and Thomas Martin Lowry in 1923. The theory is that acid can lose or donate a proton.

Which if the following is an example of a bronsted-lowry acid

NH4+

How can the placebo effect cause problems in an experiment

The placebo effect can causes the dependent variable to change without any causative reason. This distorts the results for the control set in an experiment.
