5 View Solution D) More energy is available for overcoming any activation barrier. A student observes that the rate of a reaction increases as the temperature increases. What is the reason for this? Exp 5: Emission Spectroscopy 2 When the light from a light bulb is reflected by a diffraction grating, a continuous band spectrum is obtained (like a rainbow). When the light from a metal salt in a flame is reflected from a diffraction grating, visible, discrete lines are observed. What causes this line spectra? View Solution B) Transitions of electrons between orbitals cause the visible line spectra. Tries Tol Pts 1 st 2 nd 3 rd 4 th 5 th 1/1 ±0 1 1 3
If you observe a red, green, and blue line in an atomic emission spectrum, which line represents emission from the energy level closest to its final level?

4 View Solution G) all of the above What information should you record in your notebook? 1/1 ±0 1 1 5 View Solution B) Quench the fire with your wash bottle and continue with the same applicator. What should you do if the tip of your applicator catches on fire? 1. (2 pts) For the Balmer series for the hydrogen atom a. (1 pt) List ni and nf for the four lowest energy levels. Tries Tol Pts 1 st 2 nd 3 rd 4 th 5 th b. (0.5 pts) What are the ni and nf values for the Balmer line that you expect to have
the lowest energy?
c. (0.5 pts) What are the ni and nf values for the Balmer line that you expect to have the longest wavelength?
Answer question 2 BEFORE you measure the sparkler spectrum 2. (1 pt) What might cause the wider bands of light you observe in some of the flame spectra compared to the hydrogen lamp? 3. (6 pts) Two different sparkler spectra have been given to you, each with spectra
taken close up and farther away to help you identify both strong and weak features. The off scale peak at high wavelength is centered at approximately 769 nm. Identify as many lines or bands as you can, based on comparison with your flame spectra. Put the names of the metal (Na, Li, K, Sr, Ba, and/or Cu) directly on the spectra, with an arrow
