Given the reaction below

2NOBr(g) <==> 2NO(g) + Br2(g)

and the value of Kc = 1.98, at a temperature of 480 K what is the value of Kp ?

(Hint: Use the value of R in the appropriate units.)

I used the equation Kp=Kc(RT)^Delta N

Then plugged in to get Kp=1.98(.0821x480k)^-1

I get the answer 5.02E-2

what am I doing wrong, and how do I do this correctly?
