The rate constant of the elementary reaction is at 667 \deg C, and the reaction has an activation energy of 307 k(J)/(m)ol. Compute the rate constant of the reaction at a temperature of 739 \deg C. = At a temperature of 667 \deg C, s is required for half of the originally present to be consumed. How long will it take to consume half of the reactant if an identical experiment is performed at 739 \deg C? = s

4.2.2 Quk: Slides, Text, and Graphics Question 2 of 10 Just as he was finishing a slide, Jacob found that he needed extra space for more text. To make room, he simply dropped the text size in half to 16 point. Now, he can fit all the text he needed and add a picture. What did Jacob do wrong here? A. He dropped the text size. Since the audience needs to read from a distance, slide presentations need to have a large text size. B. He should have made room for an image as opposed to more text. C. He did nothing wrong here, since he was now able to add a bit of media. D. He should have used a pie chart to better organize his thoughts. SUBMIT PREVIOUS Desk 2

let $f: R \rightarrow R'$ be a ring epimorphism and let $I$ and $J$ two ideals of a ring $R$. then ? $f(I+J) = f(I) + f(J)$ ? $f(I \cdot J) = f(I) \cdot f(J)$ ? $f(I \cap J) \subseteq f(I) \cap f(J)$ and if $ker f \subseteq I$ or $ker f \subseteq J$. then $f(I \cap J) = f(I) \cap f(J)$

Problem #4. An E&M wave having wave length of 560. nm hits a surface. Electrons were released without Kinetic energy (cut-off) i.e. this light's energy was just enough to release the electrons without speed. nm IF ANOTHER wave was used to the same surface having wave length of 400. Fm. A. What is the work function of this surface in eV? B. What is maximum kinetic energy of the emitted electrons in eV AND Joules as well as its speed? C. What is the De Broglie wave length of the emitted electrons? \lambda = 560 nm \lambda = 400 nm Problem #5. A photon of wave length of 0. 450 nm strikes a free electron that is initially at rest With ELASTIC COLLISSION. The incident photon is scattered STRAIGHT BACKWARD. A. What is the wave length of the scattered photon? B. What is the speed of the recoiled electron? \lambda_0 = 0.450 nm
