A reaction A + B --> C has K = 4.5 * 105. Achemist mixes up 0.5M A and B (no initial C). Which of thefollowing is true of our ICE table?
Please pick the best answer!
we can use the "x is negligible" assumption because K islarge
we cannot use the "x is negligible" assumption because K islarge
we can use the "x is negligible" assumption because K is largeand we are starting with reactants
