Question 2 a scientist carries out a reaction twice. in trial a, the scientist combines the reactants in a container. in trial b, the scientist combines the reactants in the same container, but she also adds a catalyst. if everything else is the same about the two trials, what is most likely true about trial b? it will produce more product than trial a. it will produce different products than trial a. it will have a lower activation energy than trial a. it will have a higher overall energy output than trial a.

We will use a video to study faraday’s law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will: examine some of the main principles behind faraday’s law. apply lenz’s law to determine the direction of the induced emf. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. use the horizontal scale provided to determine the speed of the coil. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.
