A mixture containing 0.5 mol of H2 (g) and 0.5 mol of I2 (g) was introduced into a 10L container at a temperature of 448 C. At this temperature the equilibrium constant Kp is 50. i. What is the total pressure in the container before the reaction starts and at equilibrium. ii. ...
In short: 2x^2-5x-3 becomes 2x^2-6x+x-3. Split and factorise for: 2x(x-3) 1(x-3) Which becomes: (2x+1)(x-3) x=-1/2 or x=3
Are you wanting it factorised? If so: multiply the constant, in this case '-3' by the co-efficient of x^2, so: (2x-3=6) Take the 2 off the co-efficient and replace the constant, -3, with -6, so you have: x^2 -5x -6 Find products of -6 that also add to make -5. The prod...
