2 Consider the following reaction: CS₂ (g) + 4 H₂ (g) <====> CH4 (g) + 2 H₂S (g) Calculate the value of Keq if the equilibrium concentrations are [CS₂] = 0.142, [H₂] = 0.280, [CH4] = 0.0100, and [H₂S] = 0.0200. Place your answer in the box. Express your answer using only a number or numbers without text. Report your result in scientific notation and to the proper number of significant figures. Use the following format to express a number in scientific notation: 1.23E4 (or 1.23E-4 if the exponent is negative). Note that there are no spaces within the expression. All numbers are measured.
