H3C−CH = CH2 At 700 K, the rate constant for this reaction is 6.2× 10−4 min−1. How many minutes are required for 10.0% of a sample of cyclopropane to ... WebNov 30, 2016 · We use (a3 −b3) = (a −b)(a2 + ab + b2) Therefore. (x3 − 1) = (x −1)(x2 + x + 1) = 0. (x −1) = 0 and (x2 +x +1) = 0. x = 1. For the equation, x2 + x + 1 = 0. We calculate the discriminant, Δ = b2 − 4ac = 1 −4 ⋅ 1 ⋅ 1 = −3. As, Δ > 0, we do not a solution in R but in C.
