Default Finding time



How to solve this? If can, please show the formula also. Thank you.

The time taken for the product X2Y to be formed in the reaction, 2X+Y-->X2Y , was recorded at temperature T K.

Experiment Initial Concentration Time(s)
(mol dm-3)
X Y
1 0.25 0.25 100
2 0.25 0.50 50
3 0.50 0.25 25

What is the time taken for X2Y to be formed if 0.10 mol dm-3 of X and 0.20 mol dm-3 of Y is used?

The answer given is 781 s.

Am I suppose to find the k, constant from rate=k[X][Y] first?

When you look at yourk data you should see that R = k[X}*2[Y] and thus solve for
