For a given reaction, the rate constant, k, was determined at different temperatures. To obtain a linear graph, one should plot: k vs. time ln k vs. 1/T ln k vs. ln [A] k vs. 1/T ln k vs. time ln k vs [A] 1/T vs 1/[A] [A] vs T
A chemical reaction was conducted at varying temperatures so that the equilibrium constant, K was determined at each. Thereafter it was assumed that the reaction enthalpy, DeltarxnH° was independent of temperature and a graph of 1/T (in Kelvin) vs. ln K was plotted yielding a straight line with a slope of –1586.33. What was the resulting DeltarxnH° value and was it an exothermic reaction

1)The rate law of a reaction is rate =k[X]³. The units of the rate constant areL mol-1 s-1mol² L-2 s-1mol L-1S-2L² mol-2 s-1mol L-1S-12)Given the following rate law, how does the rate of reaction change if the concentration of Z is tripled? Rate =k[X]³[Y]²[Z]⁰The rate of reaction will increase by a factor of136803)What data should be plotted to show that experimental concentration data fits a first-order reaction?1 / [reactant] vs. time[reactant] vs. timeln (k) vs. Ealn (k) vs. 1 / Tln [...
the slope of a line graph of ln k versus 1/T is -1.82 ×10^4 K what is the final temperature if it is observed that the rate constant of a reaction increases by a factor of 20 when increased from 25 deg Celsius to this higher final temperature ? (detailed solution please )
Part 2: Velocity vs. Time 1. For each velocity vs. time graph (Graph 3 and 4), describe how you would walk in order to replicate the 1-D motion graph. Use words such as away, toward, at rest, speeding up, slowing down, constant speed. Be specific with your time periods. 2. For each velocity vs. time graph, create the corresponding position and acceleration versus time graphs. Construct your graph on a computer program such as Microsoft ExcelB. If you do not...
