A question in Chemical Equillibrium
In this question is the answer D because because the slopes of the curves representing Cl2 and PCl3 should be same
I know the answer is D but dont know the reason

shouldnt it be B ?? after eqbm is achieved pcl3 and cl2 conc should be same
the 2 reactants in B are changing conc with different rates
which cant be the case here
hmm thats true too. but there still exists equal conc part
what :O why??
the rate has to be same not conc. These are conc vs time graphs, so slope needs to be zero :D ie no change wrt time which is eq
in b pcl3 is dec and cl2 is inc, which cant be possible since both of them are on product side
with the kc<2 condition we can eliminate a
between c and d, since all the reactants and products have stoi coeff 1, in c the initial conc of cl2 is less than the final conc of pcl5
which is not possible since for every 1 mol of cl2 1 mol of pcl5 will be formed so c is wrong
so that leaves us with d
Thanks for the explanation sir
