Hi! For part a, you want to look at how the partial pressures of A, B, and C change. Since A decreases by 10 kPa, B increases by 5 kPa, and C increases by 10 kPa, the coefficients of the balanced equation would be in a 2:1:2 ratio. So, the equation for part A is
2A <=> B + 2C. Then, for part b, using the equation from part a you can find the expression for Kp. Plug in the partial pressures of each substance at equilibrium (when the rate becomes constant, aka when the graph is flat to find the equilibrium constant.
I hope that helps!
