A) Differentiate ln(x) b) integrate ln(x)

A) y=ln(x) E y = x E y (dy/dx ) = 1 E ln(x) (dy/dx) = 1 X(dy/dx) = 1 Dy/dx = 1/xb) y = 1 * ln(x) V = ln(x) U= x dv/dx =1/x Du/dx = 1xln(x) - (integral) x * (1/x)xln(x) - (integral) 1= xln(x) -x + C

The formation of ammonia is an equilibrium reaction; N2(g) + 3 H2(g) <--> 2 NH3(g) the enthalpy of this reaction is negative. What can be done to increase the yield of products?
