please help me out with these questions, i need help. thank you in advance!! Question 2 (2 points) The radioactive decay of an isotope was measured for 1 week. The kinetics were modeled using a first order integrated rate law plot, such that In[amount of radioactive isotope remaining] was plotted on the y-axis and time was plotted on the x-axis. The data set was modeling using a linear equation, y=-0.542-1.92. In blank # 1, determine the rate constant for the...
please help me with the ones you can. thank you!! Solve for x in the equation: In = 10 1.3x10-4 Report your answer with 2 significant figures. A/ Question 2 (1 point) The decomposition of hydrogen peroxide is described below. 2 H2O2 (aq) → → 2 H2O (1) +O2 (g) rate = k[H202] The rate constant for the reaction is 5.3x10-4 M/s. If the initial concentration of hydrogen peroxide is 0.320 M, calculate the time it takes for the concentration...
