Chem what is q
WebAug 13, 2024 · When the rates of the forward and reverse reactions have become equal to one another, the reaction has achieved a state of balance. Chemical equilibrium is the state of a system in which the rate of the forward reaction is equal to the rate of the reverse reaction. Figure 8.2. 1: Equilibrium in reaction: H 2 ( g) + I 2 ( g) ⇌ 2 HI ( g). Webq/(mC) = ΔT, divide by m and C for both sides of the equation. So ΔT is solved for then we substitute the values in to get a numerical answer. (1.0 x 10^(2))/(10.0*0.90) = 11.111…
