Please answer all 4!! Im so lost.

Consider the following system at equilibrium where H=108kJ, and Kc=0.0129, at 600K COCl2(g)CO(g)+Cl2(g) If the VOLUME on the equilibrium system is suddenly increased at constant temperature: The value of Kc ncreases decreases remains the same The value of Qc is greater than Kc is equal to Kc is less than Kc The reaction must run in the forward direction to reestablish equilibrium. run in the reverse direction to reestablish equilibrium. remain the same. It is already at equilibrium. The number of moles of Cl2 will increase Consider the following system at equillbrium where H=10.4kJ and Kc=55.6, at 698K. H2(g)+I2(g)2HI(g) If the VOLUME of the equllibrium system is suddenly incre The value of Kc ncreases decreases remains the same The value of Qc is greater than Kc Is equal to Kc is less than Kc The reaction must run in the forward direction to reestablish equilibrium. run in the reverse direction to reestablish equilibrium. remain the same. It is already at equilibrium. The number of moles of I2 will increase decrease remain the same Consider the following system at equilibrlum where H=18.8kJ, and Kc=1.05101, at 350K: 2CH2Cl2(g)CH4(g)+CCl4(g) If the temperature on the equilibrium system is suddenly decreased: The value of Kc ncreases decreases remains the same The value of Qc is less than Ke is greater than Kc is equal to Kc The reaction must run in the forward direction to reestablish equilibrium run in the reverse direction to reestablish equilibrium remain in the current position, since it is already at equilibrium The concentration of CCl4 will increase decrease remain the same Consider the following system at equllibrlum where H=198kJ, and Kc=2.90102, at 1150K: 2SO3(g)2SO2(g)+O2(g) If the temperature on the equilibrium system is suddenly decreased: The value of Kc ncreases decreases remains the same The value of Qc is less than Kc is greater than Kc is equal to Kc The reaction must run in the forward direction to reestablish equilibrium run in the reverse direction to reestablish equilibrium remain in the current position, since it is already at equilibrium The concentration of O2 will increase decrease remain the same
