1. A test charge q=+1106C is placed halfway between a charge q1=+5106C and a charge q2=+3106C that are 10 cm apart. Find the magnitude and the direction of the resultant force on the test charge. Consider the formation of product C as shown below: 2A(g)+B(g)3C(g)+D i) A mixture of 5.2 moles of A, 8.2 moles of B, 1.45 moles of C and 1.05 moles of D is placed in a 2L container. Calculate the equilibrium constant for this reaction. ( 2 marks) ii) What is the difference between Kc and Kc ?? Calculate the Kc. (2 marks)
