Increaseing the pressure of a system will have what effect on the equilibrium of this reversable reaction 3H2 + N2 <---> 2NH3

Increaseing the pressure will cause the equilibrium to move to the right of the reaction, producing more products than reactants. This is because there is fewer gasseous moles on the right (2 moles) than the...

Find the area bounded by the curve x^3-3x^2+2x and the x-axis between x=0 and x=1.

To find the area under a curve that is bounded by the x-axis you simply need to integrate the equation of the curve between the limits, so for this equation we will integrate y=x 3 -3x 2 +2x with 1 as our up...

Differentiate ln(x^3 +2) with respect to x

The differential of ln(x) is x^-1 or 1/x. Because we have x^3 + 2 inside the bracket we have to differentiate this term also and multiply this with the other term. For example, d/dx of x^3 +2 is equal to 3x^...

A curve is defined by the parametric equations: X = 3 – 4t , y = 1 + (2/t) Find (dy/dx) in terms of t.

When dividing fractions by fractions with a common factor: (a/c) / (b/c) = (a/c) * (c/b) = (ac/bc) we can cancel the common factor to get (a/b). So in this question we can do the same: (dy/dt) / (dx/dt) = (d...
