(4+2 = 6 Points)a. The rate constant for a first-order reaction is . If one-quarter of a radioactive sample remains after 2.00 hours, what is the rate constant of its decay reaction?b. Pt-200 isotope undergoes beta decay. Write the nuclear equation for this radioactive decay.33. (4 Points)Name the following two compounds:a. an alkene with 5 carbon atoms, if you cannot visualize it, email me.b. an alkane with 4 carbons, if you cannot visualize it, email meLabel the following two compounds as an alcohol or an ether:c. CH3–CH2–O–CH2–CH2–CH2– organic compound with -OH group, email me if you have difficulty with visualizing this structure.34. (2+5 = 7 Points)a. The rate law for a reaction is as shown below:Rate = k [A]2[B]By what factor does the rate increase or decrease for the gaseous reaction if:1. Partial pressure of A is doubled while that of B is kept constant?1. Partial pressure of A is kept constant and that of B is doubled?Remember, partial pressure for a gaseous reaction is equivalent to concentration.b. Determine the rate law and find the value of rate constant (with its unit) for the following reaction given the initial rate data in the table:2 A + 2 B ?
