Consider a first order reaction at 450 K, X(g) → Y(g) + Z(g) If value of rate constant (K) from given data is x. Then value of 103 K is (Assume initially only X is present) [Take ln a = 2.3 loga and log3 = 0.5 and log2 = 0.3] pls answer fast

Astudent made the lewis dot diagram of a compound shown. what is the error in the lewis dot diagram? a)an o atom should transfer all of its six electrons to mg because the formula is mgo b) both electrons of mg should be transferred to one o adam because the formula is mgo c) the electrons should be transferred from each o add him to capital mg because mg has fewer electrons d) the number of dots around mg should be four because it has to transfer two electrons to each o

Which statement is best described as a atom

Kc = 0.040 for the system below at 450oc. if a reaction is initiated with 0.40 mole of cl2 and 0.40 mole of pcl3 in a 2.0 liter container, what is the equilibrium concentration of cl2 in the same system? pcl5(g) ⇄ pcl3(g) + cl2(g)
