Exothermic vant hoff plot

WebConsider the reversible gas phase elementary reaction. The rate law for this gas phase reaction will follow an elementary rate law. Where K c is the concentration equilibrium constant. We know from Le Chaltlier's Law that if the reaction is exothermic, K c will decrease as the temperature is increased and the reaction will be shifted back to the left. … WebThis is the van’t Hoff plot. By experimentally measuring the concentrations of reactants and products at various temperatures, making the van’t Hoff plot would yield the change in …

For a reversible reaction, the equilibrium constant can be measured at a variety of temperatures. This data can be plotted on a graph with ln Keq on the y-axis and 1/T on the x axis. The data should have a linear relationship, the equation for which can be found by fitting the data using the linear form of the Van 't Hoff equation WebFor exothermic reaction:-. ΔH=negative.
