0.200mol of H2, 0.200mol of I2, and 0.200mol of HI were placed in a 1.00 L flask and allowed to come to equilibrium. The Kc value of the reaction at this temperature is 49.5. Determine the equilibrium concentrations of all species.

c. 75.7

i think that is the right

i'm pretty sure its b i might be wrong though!

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
