Suppose the reaction in the forward direction is first order the rate constant is 1.10x10^-2 the reverse reaction is first order and the rate constant is 4.30x10^-2 at the same temperature what is the equilibrium constant?

Jenny places a strip of ph paper into a solution. when she removes the ph paper, it has turned yellow-green. what should jenny do next to determine the ph of her solution? a. use a different testing method because the ph paper should not change colors b. place the ph paper into a machine that reads the ph of the solution c. compare the ph paper's color with the color of ph paper from another solution d. compare the ph paper's color with a chart of colors and ph ranges
