(n) AG = -(2.303X1.987X7) log K (Find AG for T = 333
and K = 6.39 x 1Q5
)
C. Solving the quadratic equation. For the equation: ax
2 + bx + c = 0, the
solution is
—b ± Vb
2 - 4ac
x =
2a
Solve for the unknown variable in each of the following problems,
(o) (y + 7)
2 = 64
(p) 5x
2 - 8 = 6x - 1
(q) (z - 3)
2 = 5z - 11
(r) 4 2 + 5q = 3
(s) 7p
2 - 3p = 6
(t) (2N + 4)
2 = 7 - 4N
(u) (0.4V - 0.3)
2 = 0.16 - 0.24V
(v) 8.59*
