For the reaction : 2N_(2)O_(5)rarr4NO_(g)+O_(2)(g) if the concentration of NO_(2) increases by 5.2xx10^(-3)M in 100 sec, then the rate of reaction is :

For a reaction : 2A(g) rarr B(g) + 3C(g), rate constant of disappearance of A is 10^(-3) "M sec"^(-1) . If initially 2 M of A is taken then what will be concentration of C afterr 5 minutes?

For a zero order reaction : A rarr 2B, initial rate of a reaction is 10^(-1)"M min"^(-1) . If concentration of 'A' is 0.1 after 120 sec then what would be concentration of B after 60 sec.

For the following reaction : A(g) +B(g) rarr 2C(g) + D(g), the rate law is given as rate of disappearance A=K[A]^(2//3)[B]^(1//3) . If initial concentration of A and B are 2M each and no C and D were present initially, then the time at which total concentration (sum of concentration A, B, C, and D) will become 5.5 M, is : (Given : K = 1.386xx10^(-1)min^(-1)

For the following reaction A(g) + B(g) rarr 2C(g) + D(g), the law is given as R = [A]^(1//3).[B]^(2//3) . If initially concentration of A and B are unity then total molar concentration of all gases at t=600 sec. will be : [Given : K=2.31xx10^(-3)sec^(-1) ]

The reaction : A(g) rarr 2B(g)+C(g) is first order reaction w.r.t. A, with rate constant 1.386xx10^(-4)sec^(-1) . If initially 0.1 mole/litre of A was taken and the reaction is occurring at constant pressure and temperture then the concentration of A after 5000 sec will be:

The reaction A (g) rarr B(g) + 2C (g) is a first order reaction with rate constant 3465 xx 10^(–6) s^(–1) . Starting with 0.1 mole of A in 2 litre vessel, find the concentration of A after 200 sec., when the reaction is allowed to take place at constant pressure and temperature.
