Initial rate data at 25.0 degree C for the reaction; NH_4^+ (aq) + NO_2 rightarrow N_2(g) + H_2O (l) are shown below: Determine the rate law from the data and calculate the rate constant k at 25.0 degree C At 500 degree C, cyclopropane (C3H6) rearranges to propene (CH3CH CH_2): C3H6(g) rightarrow CH3CH CH2 (g) The reaction is first order and the rate constant is 6.7 Times 10^-4 s-1. (a) What is the rate law for the reaction, and; (b) if the initial concentration of C3H6 is 0.100 M. what is the concentration of cyclopropane of after 20 min? Butadiene (C4H6) reacts with itself at 250 degree C to form a dimer with the formula C8H12. 2C4H6 (g) rightarrow C_8H_12(l) The reaction is second order in C4H6. (a) What is the rate law for the reaction, and; (b) if the rate constant is 4.0 Times 10^-2 M-1.s-1, and the initial concentration of C_4H_6, is 0.200 M, how long will it take for the concentration of C4H6 to reach 0.04 M? In Q.2 above what is the half life for the reaction and what is concentration of C_3H_6 after 3 half-lives In 0. 3 above how long are the first and second half-lives?
