WebFinally, considering that, by equation (3), the ux owing through the rotor is pro-portional to jB~j (note that the angle in equation (3) is equal to ˇ=2; as a matter of fact the ux is assumed to be owing straight inside the motor), it turns out T = K i; (11) where K := ld=A. 1.3 The back EMF e ect WebAug 14, 2024 · Consider the reaction. H 2(g) + I 2(g) → 2HI(g) If we begin with 1.00mol of H 2 and 1.00mol of I 2 at 500K in a reaction vessel of fixed volume, we observe that, at equilibrium, nHI = 1.72mol, leaving in the equilibrium mixture nH2 = 0.14mol and nI2 = 0.14mol. Similarly, consider the decomposition reaction.
