Minta bantuannya dong sebisanya, semua juga gak papa. Terimakasih

2a. Kc =[tex] \frac{[H_{2}][ Cl_{2}] }{[HCl]^{2} } [/tex]
b. Kc = [tex] \frac{[H_{2}O]^{2}[ Br_{2}] }{[O_{2}][HBr]^{2} } [/tex]

3a. Kc = [tex] \frac{[ SO_{2}]^{2} [O_{2}] }{ [SO_{3}]^{2} } [/tex] = [tex] \frac{[ \frac{0,3}{2} ]^{2} [\frac{0,2}{2}] }{[ \frac{0,3}{2} ]^{2} } [/tex] = 0,1
