Answer:
this is a graphical question so, data has to be obtained using the graphical peaks.
0s 2s 4s 6s 8s 10s
2 2-x+3=4
X = 1 2 1 2
its clear from the trend that reaction is of 1st order since we get t0.5=2s
P = 4 2 1+3 2+3 2.5 {Since 3moles are added after every 3s interval; using second peak and t0.5=2s it can be deduced that T t= 2s; P =4}
Q = 1 1+2 1+2+1 1+2+1+2 1+2+1+2+2.5
So at t = 10s we get [P]/[Q] = 2.5/8.5 =5/17 (option d)
