Be sure to answer all parts. At 430°C, the equilibrium constant (KP) for the reaction 2NO(g) + O2(g) ⇆ 2NO2(g) is 1.5 × 105. In one experiment, the initial pressures of NO, O2, and NO2 are 9.5 × 10−3 atm, 5.5 × 10−2 atm, and 0.14 atm, respectively. Calculate QP and predict the direction that the net reaction will shift to reach equilibrium. What is QP for the experiment?

Predict whether the changes in enthalpy, entropy, and free energy will be positive or negative for the boiling of water, and explain your predictions. how does temperature affect the spontaneity of this process?

Agroup of students is studying convection current. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other is in an area with warm air. after 10 minutes, the balloon are released from a height of 1 meter. which of the following to the students most likely observe? a) the warm balloon expands and rises. the cold balloon shrinks and sinks b) the balloon both rise. the cold balloon is larger than the warm balloon c) the cold balloon expands and rises. the warm balloon shrinks and sinks d) the balloon rise at the same rate. both balloons are the same size
