The answer will be (D)

The rate would be four times larger.

when the law rate = K [NO]^2[H2]

so, for example when we assume that [NO] = 2 and K = 2 and [H2] = 1

∴ law rate = 2 * 2^2 * 1 = 8

and when the [NO] is doubled that means it becomes 4

∴ law rate = 2 * 4^2 * 1 = 32

when the first law rate = 8 and after [NO] doubled = 32

the rate would be four-time larger
