In the equilibrium system below, which of the following changes would cause the equilibrium position to shift to the right?

2so3(g) two arrows stacked on top of each other. the top arrow points to the right. the bottom arrow points to the left. 2so2(g) + o2(g) deltah = +197 kj/mol

a) decrease the temperature
b) increase the volume
c) add more o2 gas
d) add a catalyst

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
