CH3CN(g) --> CH3CN(g) The plot of ln[CH3NC] versus time in seconds produced the linear regression equation: y= -6.3x10-3(x) - 1.366 How much time does it take to reach 50% of the initial concentraion for this reaction? a.) 217 s b.) 150 s c.) 20.2 s d.) 110 s1-arr In a study of the gas phase decomposition of phosphine at 120 °C PH3(g)- →1/4 P4(g) + 3/2 H2(g) the concentration of PH3 was followed as a function of time. It was found that a graph of In[PH3] versus time in seconds gave a straight line with a slope of -2.50×10² s1 and a y-intercept of -3.24. Based on this plot, the reaction i v O order in PH, and the half life for the reaction is seconds. zero first second

Divide the concentration of HSO3 with the time in seconds to get the rate. Volume is assumed to be additive in this experiment. Thus, the total volume of all the solutins is assumed to be 20.0 mL. This introduces a small error that can be considered insignicant. The concentrations of IO; and HSO, (after mixing but before the reaction begins) can be calculated using the relationship: Mailute Vdilute= Mcone Vcone. A sample calculation is shown below for the concentration of IO, in Trial 1: Mailute to be calculated Vdilue 20.0 mL 0.020 M x 2.0 mL Mcone 0.020M V conc 2.0 mL %3D diluted [IO, ] = = 0.0020 M IO, %3D 20.0 mL Similarly, the concentration of HSO; in Trial 1 is calculated thus: 0.010 M x 2.0 mL diluted [HSO, ] =0.0010 M HSO, 20.0 mL
